NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Basis of Presentation

The accounting policies followed by Western Digital Corporation (the “Company”) are set forth in Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended July 2, 2010. In the opinion of management, all adjustments necessary to fairly state the unaudited condensed consolidated financial statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended July 2, 2010. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.

Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.

Warranty

The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated repair or replacement costs and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assists the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may materially affect operating results. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected. Changes in the warranty accrual were as follows (in millions):

	Three Months						Nine Months
	Ended						Ended
	Apr. 1,			Apr. 2,			Apr. 1,			Apr. 2,
	2011			2010			2011			2010

Warranty accrual, end of period	$	174		$	164		$	174		$	164

Accrued warranty also includes amounts classified in other liabilities of $40 million at April 1, 2011 and $41 million at July 2, 2010.

3. Income per Common Share

The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards.

The following table illustrates the computation of basic and diluted income per common share (in millions, except per share data):

	Three Months				Nine Months
	Ended				Ended
	Apr. 1,		Apr. 2,		Apr. 1,		Apr. 2,
	2011		2010		2011		2010
Net income	$	146	$	400	$	568	$	1,118
Weighted average shares outstanding:
Basic		232		229		231		227
Employee stock options and other		4		5		4		5
Diluted		236		234		235		232
Income per common share:
Basic	$	0.63	$	1.75	$	2.46	$	4.93
Diluted	$	0.62	$	1.71	$	2.42	$	4.82
Anti-dilutive potential common shares excluded*		4		1		4		1

* For purposes of computing diluted income per common share, certain potentially dilutive securities have been excluded from the calculation because their effect would have been anti-dilutive.

4. Debt

In February 2008, Western Digital Technologies, Inc. (“WDTI”), a wholly-owned subsidiary of the Company, entered into a five-year credit agreement that provided for a $500 million term loan facility. As of April 1, 2011, the term loan facility had a variable interest rate of 1.56% and a remaining balance of $325 million, which requires principal payments totaling $31 million through the remainder of 2011, $144 million in 2012 and $150 million in 2013. The term loan facility has a maturity date of February 11, 2013. As of April 1, 2011, WDTI was in compliance with all covenants.

See Note 10 for additional disclosures related to the Company’s new credit facility to be entered into in connection with the closing of the planned acquisition of Viviti Technologies Ltd., until recently known as Hitachi Global Storage Technologies Pte. Ltd.

5. Legal Proceedings

The Company discloses material loss contingencies deemed to be reasonably possible and accrues for loss contingencies when, in consultation with the Company’s legal advisors, the Company concludes that a loss is probable and reasonably estimable. Except as otherwise indicated, the possible losses relating to the matters described below are not reasonably estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.

Intellectual Property Litigation

On June 20, 2008, plaintiff Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against the Company and two other companies alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. Convolve is seeking unspecified monetary damages and injunctive relief. On October 10, 2008, Convolve amended its complaint to allege infringement of only the ‘473 patent. The ‘473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. A trial in the matter is scheduled to begin on July 5, 2011. The Company intends to defend itself vigorously in this matter.

7

On July 15, 2009, plaintiffs Carl B. Collins and Farzin Davanloo filed a complaint in the Eastern District of Texas against the Company and ten other companies alleging infringement of U.S. Patent Nos. 5,411,797 and 5,478,650. Plaintiffs are seeking injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to nanophase diamond films. The Company intends to defend itself vigorously in this matter.

On December 7, 2009, plaintiff Nazomi Communications filed a complaint in the Eastern District of Texas against the Company and seven other companies alleging infringement of U.S. Patent Nos. 7,080,362 and 7,225,436. Plaintiffs are seeking injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to processor cores capable of Java hardware acceleration. The Company intends to defend itself vigorously in this matter.

On January 5, 2010, plaintiff Enova Technology Corporation filed a complaint in the District of Delaware against the Company and Initio Corporation alleging infringement of U.S. Patent Nos. 7,136,995 and 7,386,734. Plaintiff is seeking injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to real time full disk encryption application specific integrated circuits, or ASICs. The Company intends to defend itself vigorously in this matter.

On November 10, 2010, plaintiff Rembrandt Data Storage filed a complaint in the Western District of Wisconsin against the Company alleging infringement of U.S. Patent Nos. 5,995,342 and 6,195,232. Plaintiff is seeking injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to specific thin film heads having solenoid coils. The Company intends to defend itself vigorously in this matter.

On October 4, 2006, plaintiff Seagate Technology LLC (“Seagate”) filed a complaint against the Company and one of its employees formerly employed by Seagate in the Minnesota Fourth Judicial District Court. The complaint alleges claims based on supposed misappropriation of trade secrets and seeks injunctive relief and unspecified monetary damages, fees and costs. On June 19, 2007, the Company’s employee filed a demand for arbitration with the American Arbitration Association. A motion to stay the litigation as against all defendants and to compel arbitration of all Seagate’s claims was granted on September 19, 2007. The parties are engaged in arbitration, and discovery in the arbitration proceeding is ongoing. On September 23, 2010, Seagate filed a motion to amend its claims and add allegations based on the supposed misappropriation of additional confidential information. The arbitrator granted Seagate’s motion, and the plenary hearing in the arbitration is now set to begin in May 2011. The Company intends to continue to defend itself vigorously in this matter.

Employment Litigation

On March 20, 2009, plaintiff Ghazala H. Durrani, a former employee of the Company, filed a putative class action complaint in the Alameda County (California) Superior Court. The complaint alleged that certain of the Company’s engineers had been misclassified as exempt employees under California state law and were, therefore, due unspecified amounts for unpaid hourly overtime wages and other amounts, as well as penalties for allegedly missed meal and rest periods. By court order dated April 24, 2009, the case was transferred to the Orange County (California) Superior Court. On or about June 16, 2009, the Company was dismissed from the case without prejudice by stipulation, leaving WDTI as the sole remaining defendant. On or about June 4, 2009, WDTI filed its answer to the complaint, denying the substantive allegations thereof and raising several affirmative defenses. The parties participated in a mediation of the case on June 3, 2010, which led to a proposed settlement of the case. The proposed settlement, which was ultimately approved by the court, resolved the case on a class-wide basis for an immaterial amount that was accrued by the Company in the fourth quarter of fiscal 2010. The court granted final approval of the settlement and entered judgment on February 7, 2011. At the Final Accounting Hearing scheduled for July 11, 2011, the court is expected to confirm that the settlement amount was fully paid in accordance with the settlement agreement. After that hearing, the lawsuit will be formally concluded and dismissed.

8

On February 26, 2010, and as thereafter amended on August 23, 2010 and December 22, 2010, plaintiff Tarriq Sadaat, a former employee of the Company, filed a putative class action complaint in the Orange County (California) Superior Court against the Company; WDTI; Kelly Services, Inc., a Delaware corporation (“Kelly Services”); and certain other unnamed individuals. The named plaintiff seeks to represent certain hourly employees who were assigned to work at certain of the Company’s facilities by Kelly Services, a temporary staffing agency. In this regard, the complaint alleges that the hourly employees are due unspecified sums for unpaid overtime wages and other amounts, as well as penalties for allegedly missed meal and rest periods. The complaint seeks unspecified damages including lost wages, penalties under the California Labor Code and other statutes, compensatory and punitive damages, declaratory relief, injunctive relief, interest, attorneys’ fees and costs. The Company’s response to the complaint was filed and served in January 2011. The Company denies the allegations and intends to defend itself vigorously.

Other Matters

In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

6. Income Taxes

The Company’s income tax provision for the three months ended April 1, 2011 was $13 million as compared to $40 million in the prior-year period. The Company’s income tax provision for the nine months ended April 1, 2011 was $41 million as compared to $110 million in the prior-year period. The tax provision for the three and nine months ended April 1, 2011 reflects the retroactive extension of the research and development tax credit that was signed into law in December 2010. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia and Thailand that expire at various dates through 2023 and the current year generation of income tax credits.

In the three months ended April 1, 2011, the Company recognized a net increase of $6 million in its liability for unrecognized tax benefits. As of April 1, 2011, the Company had a recorded liability for unrecognized tax benefits of approximately $246 million. Interest and penalties recognized on such amounts were not material.

The United States Internal Revenue Service (“IRS”) is currently examining fiscal years 2006 and 2007 for the Company and calendar years 2005 and 2006 for Komag, Incorporated (“Komag”), which was acquired by the Company on September 5, 2007. The IRS has completed its field work and proposed certain adjustments. Certain issues have been agreed upon by the Company and the IRS and certain issues remain unresolved. The Company has received Revenue Agent Reports (“RARs”) for the agreed issues. The Company has also received RARs from the IRS for the unresolved issues which seek adjustments to income before income taxes of approximately $970 million for the Company and $380 million for Komag. The issues in dispute relate primarily to transfer pricing and certain other intercompany transactions. The Company strongly disagrees with the proposed adjustments and is contesting them.

The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of April 1, 2011, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months.

7. Fair Value Measurements

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:

Level 1.Quoted prices in active markets for identical assets or liabilities.

9

Level 2.Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3.Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

The following table presents information about the Company’s financial assets that are measured at fair value on a recurring basis as of April 1, 2011, and indicates the fair value hierarchy of the valuation techniques utilized to determine such value (in millions):

	Fair Value Measurements at
	Reporting Date Using
	Quoted Prices
	in Active		Significant
	Markets for		Other		Significant
	Identical		Observable		Unobservable
	Assets		Inputs		Inputs

Total assets at fair value	$	1,080	$	232	$	15	$	1,327

Money Market Funds.The Company’s money market funds are funds that invest in U.S. Treasury securities and are recorded within cash and cash equivalents in the condensed consolidated balance sheets. Money market funds are valued based on quoted market prices.

U.S. Treasury Securities.The Company’s U.S. Treasury securities are investments in Treasury bills with original maturities of three months or less, are held in custody by a third party and are recorded within cash and cash equivalents in the condensed consolidated balance sheets. U.S. Treasury securities are valued using a market approach which is based on observable inputs including market interest rates from multiple pricing sources.

U.S. Government Agency Securities.The Company’s U.S. Government agency securities are investments in fixed income securities sponsored by the U.S. Government with original maturities of three months or less, are held in custody by a third party and are recorded within cash and cash equivalents in the condensed consolidated balance sheets. U.S. Government agency securities are valued using a market approach which is based on observable inputs including market interest rates from multiple pricing sources.

Auction-Rate Securities.The Company’s auction-rate securities have maturity dates through 2050, are primarily backed by insurance products and are accounted for as available-for-sale securities. These investments are expected to be held until secondary markets become available and as a result, are classified as long-term investments and recorded within other non-current assets in the condensed consolidated balance sheets. Auction-rate securities are valued using an income approach which is based on a discounted cash flow model or a credit default model. The inputs to the discounted cash flow model include market interest rates and a discount factor to reflect the illiquidity of the investments. The inputs to the credit default model include market interest rates, yields of similar securities, and probability-weighted assumptions related to the creditworthiness of the underlying assets.

Foreign Exchange Contracts.The Company’s foreign exchange contracts are short-term contracts to hedge the Company’s foreign currency risk related to the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling. Foreign exchange contracts are classified within other current assets in the condensed consolidated balance sheets. Foreign exchange contracts are valued using an income approach which is based on a present value of future cash flows model. The market-based observable inputs for the model include forward rates and credit default swap rates.

In the nine months ended April 1, 2011, there were no changes in Level 3 financial assets measured on a recurring basis. The Company had no liabilities that were re-measured and reported at fair value on a recurring basis at April 1, 2011.

The carrying amounts of cash, accounts receivable, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities. The carrying amount of debt approximates fair value because of its variable interest rate.

8. Foreign Exchange Contracts

Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. As of April 1, 2011, the Company had outstanding foreign exchange contracts with commercial banks for Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges. Thai Baht contracts are designated as either cash flow or fair value hedges.

If the derivative is designated as a cash flow hedge, the effective portion of the change in fair value of the derivative is initially deferred in other comprehensive income (loss), net of tax. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. As of April 1, 2011, the net amount of existing gains expected to be reclassified into earnings within the next 12 months was $8 million. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial.

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were not material to the condensed consolidated financial statements.

As of April 1, 2011, the Company did not have any foreign exchange contracts with credit-risk-related contingent features. The Company opened $728 million and $2.7 billion, and closed $810 million and $2.4 billion, in foreign exchange contracts in the three and nine months ended April 1, 2011, respectively. The fair value and balance sheet location of such contracts were as follows (in millions):

9. Stock-Based Compensation

The Company granted approximately 0.9 million restricted stock units during the nine months ended April 1, 2011, which are payable in an equal number of shares of the Company’s common stock at the time of vesting of the units. The aggregate fair value of the shares underlying the restricted stock unit awards was $25 million at the date of grant. These amounts are being recognized as expense over the corresponding vesting periods. For purposes of valuing these awards for the three and nine months ended April 1, 2011, the Company has assumed forfeiture rates of 2.7% and 2.1%, respectively, based on a historical analysis indicating forfeitures for these types of awards.

For the three and nine months ended April 1, 2011, the Company recognized $8 million and $25 million, respectively, in expense related to the vesting of restricted stock unit awards compared to $6 million and $16 million in the comparative prior-year periods. During the three and nine months ended April 1, 2011, the Company recognized $9 million and $29 million, respectively, in expense related to the vesting of stock options issued under stock option plans and the ESPP, compared to $10 million and $27 million in the comparative prior-year periods.

As of April 1, 2011, the aggregate unamortized fair value of all unvested restricted stock unit awards was $49 million, which will be recognized on a straight-line basis over a weighted average vesting period of approximately 1.6 years. At April 1, 2011, total compensation cost related to unvested stock options and ESPP rights issued to employees but not yet recognized was $67 million and will be amortized on a straight-line basis over a weighted average service period of approximately 2.3 years.

Stock Option Activity

The following table summarizes activity under the Company’s stock option plans (in millions, except per share amounts and remaining contractual lives):

						Weighted Average
				Weighted Average		Remaining		Aggregate
	Number			Exercise Price		Contractual Life		Intrinsic
	of Shares			Per Share		(in years)		Value
Options outstanding at July 2, 2010		9.4		$	20.61
Granted		2.4			26.14
Exercised		(0.1	)		12.21
Canceled or expired		(0.1	)		27.04
Options outstanding at October 1, 2010		11.6		$	21.82
Granted		0.1			33.27
Exercised		(0.4	)		14.04
Canceled or expired		(0.1	)		24.42
Options outstanding at December 31, 2010		11.2		$	22.21
Granted		—			—
Exercised		(0.6	)		18.65
Canceled or expired		(0.1	)		28.41
Options outstanding at April 1, 2011		10.5		$	22.35		4.8	$	166
Exercisable at April 1, 2011		5.3		$	18.96		4.0	$	102
Vested and expected to vest after April 1, 2011		10.4		$	22.33		4.8	$	164

The aggregate intrinsic value is calculated based on the difference between the exercise price of the underlying options and the quoted price of the Company’s common stock for those awards that have an exercise price below the quoted price on the date the intrinsic value is determined. As of April 1, 2011, the Company had options outstanding to purchase an aggregate of 10.4 million shares with an exercise price below the quoted price of the Company’s stock on that date resulting in an aggregate intrinsic value of $166 million. During the three and nine months ended April 1, 2011, the aggregate intrinsic value of options exercised under the Company’s stock option plans was $9 million and $20 million, respectively, determined as of the date of exercise, compared to $13 million and $63 million in the comparative prior-year periods.

Fair Value Disclosure—Stock Options and ESPP

The fair value of stock options granted is estimated using a binomial option-pricing model. The binomial model requires the input of highly subjective assumptions including the expected stock price volatility, the expected price multiple at which employees are likely to exercise stock options and the expected employee termination rate. The Company uses historical data to estimate option exercise, employee termination, and expected stock price volatility within the binomial model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options granted was estimated using the following weighted average assumptions:

	Three Months Ended		Nine Months Ended
	Apr. 1,	Apr. 2,	Apr. 1,	Apr. 2,
	2011	2010	2011	2010
Suboptimal exercise factor	1.81	1.79	1.81	1.73
Range of risk-free interest rates	0.27% to 2.90%	0.46% to 3.40%	0.26% to 2.90%	0.37% to 3.40%
Range of expected stock price volatility	0.41 to 0.56	0.40 to 0.61	0.41 to 0.59	0.40 to 0.72
Weighted average expected volatility	0.49	0.52	0.52	0.57
Post-vesting termination rate	2.95%	2.91%	2.44%	3.59%
Dividend yield	—	—	—	—
Fair value	$14.71	$17.28	$11.39	$17.10

The weighted average expected term of the Company’s stock options granted during the three and nine months ended April 1, 2011 was 5.0 years and 4.7 years, respectively, compared to 4.8 years and 4.6 years in the comparative prior-year periods.

The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The Black-Scholes-Merton option-pricing model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the current ESPP provisions are granted on either June 1 or December 1. ESPP activity was immaterial to the condensed consolidated financial statements for the three and nine months ended April 1, 2011 and April 2, 2010.

10. Planned Acquisition

On March 7, 2011, the Company entered into a stock purchase agreement (the “Purchase Agreement”) with Hitachi, Ltd. (“Hitachi”), Viviti Technologies Ltd., until recently known as Hitachi Global Storage Technologies Holdings Pte. Ltd., a wholly owned subsidiary of Hitachi (“HGST”), and Western Digital Ireland, Ltd., an indirect wholly owned subsidiary of the Company (“WDI”). Pursuant to the Purchase Agreement, WDI agreed to acquire all of the issued and outstanding paid-up share capital of HGST from Hitachi. The planned acquisition is intended to result in a more efficient and innovative customer-focused storage company, with significant operating scale, strong global talent and the industry’s broadest product lineup backed by a rich technology portfolio. The aggregate purchase price of the planned acquisition is estimated to be approximately $4.3 billion, due at closing, and will be funded with existing cash, new debt, and 25 million newly issued shares of the Company’s common stock. The Purchase Agreement contains certain termination rights for both the Company and Hitachi, including the right to terminate the Purchase Agreement if the planned acquisition has not closed by March 7, 2012. If the planned acquisition has not closed by March 7, 2012 due to the failure to receive any required antitrust or competition authority’s consent, approval or clearance or any action by any certain governmental entities to prevent the planned acquisition for antitrust or competition reasons, the Company will, concurrently with such termination, pay Hitachi a fee of $250 million in cash. The planned acquisition, which is subject to customary closing conditions, including regulatory approvals, is expected to close in the Company’s first quarter of fiscal 2012.

During the three months ended April 1, 2011, the Company incurred $10 million of expenses related to the planned acquisition of HGST which are included within selling, general, and administrative expense on the condensed consolidated statements of income.

13

On March 7, 2011, in connection with the planned acquisition of HGST, the Company, WDTI and WDI entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated regarding a new credit facility for an amount of $2.5 billion, consisting of a $500 million revolving credit facility and $2.0 billion in term loans, to be entered into in connection with the closing of the planned acquisition (the “Senior Facility”). Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated has led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, the Company, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions including completion of the acquisition in accordance with its terms, the Company, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group.

11. Recent Accounting Pronouncements

In September 2009, the FASB issued Accounting Standards Update (“ASU”) 2009-13, “Multiple-Deliverable Revenue Arrangements” (“ASU 2009-13”), and ASU 2009-14, “Certain Revenue Arrangements That Include Software Elements” (“ASU 2009-14”). ASU 2009-13 amends the revenue guidance under Subtopic 605-25, “Multiple Element Arrangements,” and addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting and how arrangement consideration shall be measured and allocated to the separate units of accounting in the arrangement. ASU 2009-14 excludes tangible products containing software components and non-software components that function together to deliver the product’s essential functionality from the scope of Subtopic 985-605, “Revenue Recognition.” ASU 2009-13 and ASU 2009-14 are effective for fiscal periods beginning on or after June 15, 2010, which for the Company was the first quarter of fiscal 2011. The Company’s adoption of ASU 2009-13 and ASU 2009-14 had no impact on its condensed consolidated financial statements.

Our Company

We design, develop, manufacture and sell hard drives. A hard drive is a device that uses one or more rotating magnetic disks (“magnetic media”) to store and allow fast access to data. Hard drives are key components of computers, including desktop and notebook computers (“PCs”), data storage subsystems and many consumer electronic (“CE”) devices.

We sell our products worldwide to original equipment manufacturers (“OEMs”) and original design manufacturers (“ODMs”) for use in computer systems, subsystems or CE devices, and to distributors, resellers and retailers. Our hard drives are used in desktop computers, notebook computers, and in enterprise applications such as servers, workstations, network attached storage, storage area networks, video surveillance equipment and cloud computing environments. Additionally, our hard drives are used in CE applications such as digital video recorders and satellite and cable set-top boxes. We also sell our hard drives as stand-alone storage products by integrating them into finished enclosures, embedding application software and offering the products as WD^®-branded external storage appliances for personal data backup and portable or expanded storage for digital music, photographs, video and other digital data.

15

Hard drives provide non-volatile data storage, which means that the data remains present when power is no longer applied to the device. Our hard drives currently include 2.5-inch and 3.5-inch form factor drives, having capacities ranging from 80 gigabytes (“GB”) to 3 terabytes (“TB”), nominal rotation speeds up to 10,000 revolutions per minute (“RPM”), and offer interfaces including Enhanced Integrated Drive Electronics (“EIDE”), Serial Advanced Technology Attachment (“SATA”) and Serial Attached SCSI (Small Computer System Interface) (“SAS”). We also embed our hard drives into WD^®-branded external storage appliances using interfaces such as Universal Serial Bus (“USB”) 2.0, USB 3.0, external SATA, FireWire^tm and Ethernet network connections with capacities of 160 GB up to 8 TB. In addition, we offer a family of hard drives specifically designed to consume substantially less power than standard drives, utilizing our WD GreenPower Technology^tm.

In October 2010, we began shipping our 3.5-inch WD Caviar^® Green^tm 3 TB drive, a SATA hard drive utilizing 750 GB-per-platter areal density and Advanced Format technology.

We also design, develop, manufacture and sell solid-state drives and media players. A solid-state drive is a storage device that uses semiconductor, non-volatile media, rather than magnetic media and magnetic heads, to store and allow fast access to data. We sell our solid-state drives worldwide to OEMs and distributors for use in the embedded systems and client PC markets. A media player is a device that connects to a user’s television, the Internet and/or home theater system and plays digital movies, music and photos from an integrated hard drive, any of our WD^®-branded external hard drives, or other USB mass storage devices or content services accessed over the Internet. We sell our media players worldwide to resellers and retailers under the WD^®brand.

Planned Acquisition of Hitachi Global Storage Technologies

On March 7, 2011, we entered into a stock purchase agreement (the “Purchase Agreement”) with Hitachi, Ltd. (“Hitachi”), Viviti Technologies Ltd., until recently known as Hitachi Global Storage Technologies Holdings Pte. Ltd., a wholly owned subsidiary of Hitachi (“HGST”), and Western Digital Ireland, Ltd., our indirect wholly owned subsidiary (“WDI”). Pursuant to the Purchase Agreement, WDI agreed to acquire all of the issued and outstanding paid-up share capital of HGST from Hitachi. The planned acquisition is intended to result in a more efficient and innovative customer-focused storage company, with significant operating scale, strong global talent and the industry’s broadest product lineup backed by a rich technology portfolio. The aggregate purchase price of the planned acquisition is estimated to be approximately $4.3 billion, due at closing, and will be funded with existing cash, new debt, and 25 million newly issued shares of our common stock. The Purchase Agreement contains certain termination rights for both us and Hitachi, including the right to terminate the Purchase Agreement if the planned acquisition has not closed by March 7, 2012. If the planned acquisition has not closed by March 7, 2012 due to the failure to receive any required antitrust or competition authority’s consent, approval or clearance or any action by any certain governmental entities to prevent the planned acquisition for antitrust or competition reasons, we will, concurrently with such termination, pay Hitachi a fee of $250 million in cash. The planned acquisition, which is subject to customary closing conditions, including regulatory approvals, is expected to close in our first quarter of fiscal 2012.

On March 7, 2011, in connection with the planned acquisition of HGST, WD, Western Digital Technologies, Inc. (“WDTI”), our wholly-owned subsidiary, and WDI entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated regarding a new credit facility for an amount of $2.5 billion, consisting of a $500 million revolving credit facility and $2.0 billion in term loans, to be entered into in connection with the closing of the planned acquisition (the “Senior Facility”). Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated has led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, WD, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions including completion of the acquisition in accordance with the terms, WD, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group.

Third Quarter Overview

For the March quarter, we believe that overall hard drive industry shipments totaled approximately 160 million units, down 2% from the prior-year period and 5% sequentially from the December quarter. We also believe that the decrease in the March quarter from the December quarter resulted from normal seasonal declines and inventory adjustments in PC manufacturers’ pipeline early in the quarter, partially offset by customers’ accelerated product purchases in the last three weeks of the quarter due to supply concerns as a result of the March 11, 2011 earthquake in Japan and related events.

The following table sets forth, for the periods presented, selected summary information from our condensed consolidated statements of income by dollars and percentage of net revenue (in millions, except percentages):

	Three Months Ended								Nine Months Ended
	Apr. 1,				Apr. 2,				Apr. 1,				Apr. 2,
	2011				2010				2011				2010

Net income		146	6.5			400	15.1			568	8.0			1,118	15.0

The following is a summary of our financial performance for the third quarter of 2011:

• Consolidated net revenue totaled $2.3 billion.

• 64% of our hard drive revenue was derived from non-desktop markets, including notebook computers, CE products, enterprise applications and WD^®-branded products, as compared to 62% in the prior-year period.

• Hard drive unit shipments decreased by 3% over the prior-year period to 49.8 million units.

• Gross margin decreased to 18.2%, compared to 25.2% for the prior-year period.

• Operating income, including $10 million of expenses related to the planned acquisition of HGST, was $158 million, a decrease of $283 million from the prior-year period.

• We generated $313 million in cash flow from operations in the third quarter of 2011, and we finished the quarter with $3.2 billion in cash and cash equivalents.

Historically, the June quarter hard drive industry unit demand has been seasonally flat to slightly down when compared to March volumes. We believe that overall hard drive industry unit shipments for the June quarter will be supply constrained as a result of the earthquake in Japan and related events; however, we are planning a normal seasonal June quarter and therefore, expect our net revenue in the June quarter to be flat to slightly down from the March quarter.

* Based on sales of hard drive units only.

For the quarter ended April 1, 2011, net revenue was $2.3 billion, a decrease of 15% from the prior-year period. Total hard drive shipments decreased to 49.8 million units for the quarter ended April 1, 2011 as compared to 51.1 million units in the prior-year period. The decrease in net revenue resulted from a $6 decrease in average selling price (“ASP”) from $51 to $45 and the decrease in unit shipments. For the nine months ended April 1, 2011, net revenue was $7.1 billion, a decrease of 5% from the prior-year period. Total hard drive shipments increased to 152.8 million units for the nine months ended April 1, 2011, as compared to 144.7 million units for the prior-year period. The decrease in net revenue resulted primarily from a $5 decrease in ASP from $51 to $46, partially offset by the increase in unit shipments. The decrease in ASP for the three and nine months ended April 1, 2011 as compared to the prior-year periods was a result of a competitive pricing environment.

Changes in revenue by geography and channel generally reflect normal fluctuations in market demand and competitive dynamics. For the three and nine months ended April 1, 2011, no single customer accounted for 10%, or more, of our revenue.

In accordance with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For the three and nine months ended April 1, 2011, these programs represented 12% and 11% of gross revenues, respectively, compared to 8% and 7%, respectively, in both the comparative prior-year periods. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product.

For the three months ended April 1, 2011, gross margin as a percentage of revenue decreased to 18.2% as compared to 25.2% for the prior-year period. For the nine months ended April 1, 2011, gross margin as a percentage of revenue decreased to 18.6% as compared to 25.0% for the prior-year period. These decreases were a result of a competitive pricing environment.

R&D expense	$	179	$	160		12	%	$	515	$	456		13	%
SG&A expense		73		64		14			198		177		12
Total operating expenses	$	252	$	224				$	713	$	633

Research and development (“R&D”) expense was $179 million for the three months ended April 1, 2011, an increase of $19 million over the prior-year period. For the nine months ended April 1, 2011, R&D expense was $515 million, an increase of $59 million over the prior-year period. As a percentage of net revenue, R&D expense increased to 7.9% and 7.2% in the three and nine months ended April 1, 2011, respectively, compared to 6.1% in both of the comparative prior-year periods. These increases were primarily due to the continued investment in product development to support new programs.

Selling, general and administrative (“SG&A”) expense was $73 million for the three months ended April 1, 2011, an increase of $9 million over the prior-year period. SG&A expense as a percentage of net revenue increased to 3.2% in the three months ended April 1, 2011, compared to 2.4% in the comparative prior-year period. This increase was primarily due to expenses related to the planned acquisition of HGST. For the nine months ended April 1, 2011, SG&A expense was $198 million, an increase of $21 million over the prior-year period. SG&A expense as a percentage of net revenue increased to 2.8% in the nine months ended April 1, 2011, compared to 2.4% in the comparative prior-year period. This increase was primarily due to expenses related to the planned acquisition of HGST and the expansion of sales and marketing to support new products and growing markets.

Other Income (Expense)

Interest income for the three months ended April 1, 2011 was $2 million, an increase of $1 million compared to the prior-year period. Interest income for the nine months ended April 1, 2011 was $6 million, an increase of $3 million compared to the prior-year period. These increases were primarily due to higher average daily invested cash balances for the periods as compared to the prior-year periods. Interest and other expense for the three and nine months ended April 1, 2011 decreased by $1 million and $2 million, respectively, as compared to the prior-year periods, primarily due to a lower amount of debt during the three months ended April 1, 2011 as compared to the prior-year period.

Income Tax Provision

Our income tax provision for the three months ended April 1, 2011 was $13 million as compared to $40 million in the prior-year period. Our income tax provision for the nine months ended April 1, 2011 was $41 million as compared to $110 million in the prior-year period. Our tax provision for the three and nine months ended April 1, 2011 reflects the retroactive extension of the R&D tax credit that was signed into law in December 2010. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia and Thailand that expire at various dates through 2023 and the current year generation of income tax credits.

In the three months ended April 1, 2011, we recognized a net increase of $6 million in our liability for unrecognized tax benefits. As of April 1, 2011, we had a recorded liability for unrecognized tax benefits of approximately $246 million. Interest and penalties recognized on such amounts were not material.

19

The United States Internal Revenue Service (“IRS”) is currently examining our fiscal years 2006 and 2007 and calendar years 2005 and 2006 for Komag, Incorporated (“Komag”), which was acquired by us on September 5, 2007. The IRS has completed its field work and proposed certain adjustments. Certain issues have been agreed upon by us and the IRS and certain issues remain unresolved. We have received Revenue Agent Reports (“RARs”) for the agreed issues. We have also received RARs from the IRS for the unresolved issues which seek adjustments to our income before income taxes of approximately $970 million and $380 million for Komag. The issues in dispute relate primarily to transfer pricing and certain other intercompany transactions. We strongly disagree with the proposed adjustments and are contesting them.

We believe that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in our tax audits are resolved in a manner not consistent with management’s expectations, we could be required to adjust our provision for income taxes in the period such resolution occurs. As of April 1, 2011, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months.

Liquidity and Capital Resources

We ended the third quarter of fiscal 2011 with total cash and cash equivalents of $3.2 billion. The following table summarizes our statements of cash flows (in millions):

	Nine Months Ended
	Apr. 1,			Apr. 2,
	2011			2010
Net cash flow provided by (used in):
Operating activities	$	1,208		$	1,579
Investing activities		(625	)		(548	)
Financing activities		(87	)		1
Net increase in cash and cash equivalents	$	496		$	1,032

Our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing return through the full investment of available funds. We believe our current cash, cash equivalents and cash generated from operations will be sufficient to meet our working capital and capital expenditure needs through the foreseeable future. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Part II, Item 1A of this Quarterly Report on Form 10-Q.

Operating Activities

Net cash provided by operating activities during the nine months ended April 1, 2011 was $1.2 billion as compared to $1.6 billion during the nine months ended April 2, 2010. Cash flow from operating activities consists of net income, adjusted for non-cash charges, plus or minus working capital changes. This represents our principal source of cash. Net cash provided by working capital changes was $130 million for the nine months ended April 1, 2011 as compared to $44 million for the prior-year period.

Our working capital requirements primarily depend on the effective management of our cash conversion cycle, which measures how quickly we can convert our products into cash through sales. The cash conversion cycles were as follows:

	Three Months Ended
	Apr. 1,			Apr. 2,
	2011			2010
Days sales outstanding		47			43
Days in inventory		28			23
Days payables outstanding		(73	)		(69	)
Cash conversion cycle		2			(3	)

For the three months ended April 1, 2011, our days sales outstanding (“DSOs”) increased by 4 days, days in inventory (“DIOs”) increased by 5 days, and days payable outstanding (“DPOs”) increased by 4 days as compared to the prior-year period. The increase in DSOs was primarily a result of changes in the linearity of shipments in the current quarter as compared to the prior-year period. The increase in DIOs was primarily due to the timing of inventory builds. The June 2010 acquisition of additional magnetic media sputtering operations also contributed slightly to the increases in DIOs and DPOs. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.

20

Investing Activities

Cash used in investing activities for the nine months ended April 1, 2011 consisted of $625 million of capital expenditures. Net cash used in investing activities for the nine months ended April 2, 2010 was $548 million which consisted of capital expenditures of $552 million, partially offset by sales and maturities of investments of $4 million.

For fiscal 2011, we expect capital expenditures to be between $775 million and $800 million, including approximately $100 million related to the conversion of our head wafer fabrication facilities to utilize 8-inch wafers from 6-inch wafers and minor expenditures to optimize the output from our magnetic media sputtering operations that were acquired in June 2010. We expect depreciation and amortization to be approximately $610 million for fiscal 2011.

Our cash equivalents are invested in highly liquid money market funds that are invested in U.S. Treasury securities, U.S. Treasury bills and U.S. Government agency securities. We also have auction-rate securities that are classified as long-term investments as they are expected to be held until secondary markets become available. These investments are currently accounted for as available-for-sale securities and recorded at fair value within other non-current assets in the condensed consolidated balance sheets. The estimated market values of these investments are subject to fluctuation. The carrying value of our investments in auction-rate securities was $15 million as of April 1, 2011.

Financing Activities

Net cash used in financing activities for the nine months ended April 1, 2011 was $87 million as compared to $1 million provided by financing activities in the prior-year period. Net cash used in financing activities for the nine months ended April 1, 2011 consisted of $75 million used to repay long-term debt and $50 million used to repurchase shares of our common stock, offset by a net $38 million related to employee stock plans. Net cash provided by financing activities for the nine months ended April 2, 2010 consisted of a net $58 million related to employee stock plans, offset by $57 million used to repay long-term debt.

Off-Balance Sheet Arrangements

Other than facility lease commitments incurred in the normal course of business and certain indemnification provisions (see “Contractual Obligations and Commitments” below), we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in our unaudited condensed consolidated financial statements. Additionally, we do not have an interest in, or relationships with, any special-purpose entities.

Contractual Obligations and Commitments

Long-Term Debt— In February 2008, WDTI entered into a five-year credit agreement that provided for a $500 million term loan facility. As of April 1, 2011, the remaining balance of the term loan facility was $325 million, which requires principal payments totaling $31 million through the remainder of 2011, $144 million in 2012 and $150 million in 2013. See Part I, Item 1, Note 4 in the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

On March 7, 2011, in connection with the planned acquisition of HGST, WD, WDTI and WDI entered into a commitment letter for the Senior Facility. Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated has led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, WD, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions including completion of the acquisition in accordance with the terms, WD, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group.

21

Purchase Orders— In the normal course of business, we enter into purchase orders with suppliers for the purchase of hard drive components used to manufacture our products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. We also enter into purchase orders with suppliers for capital equipment that are recorded as a liability upon receipt of the equipment. Our ability to change or cancel a capital equipment purchase order without penalty depends on the nature of the equipment being ordered. In some cases, we may be obligated to pay for certain costs related to changes to, or cancellation of, a purchase order, such as costs incurred for raw materials or work in process of components or capital equipment.

We have entered into long-term purchase agreements with various component suppliers, which contain minimum quantity requirements. However, the dollar amount of the purchases may depend on the specific products ordered, achievement of pre-defined quantity or quality specifications or future price negotiations. We have also entered into long-term purchase agreements with various component suppliers that carry fixed volumes and pricing which obligate us to make certain future purchases, contingent on certain conditions of performance, quality and technology of the vendor’s components.

We enter into, from time to time, other long-term purchase agreements for components with certain vendors. Generally, future purchases under these agreements are not fixed and determinable as they depend on our overall unit volume requirements and are contingent upon the prices, technology and quality of the supplier’s products remaining competitive.

See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — “Contractual Obligations and Commitments” in our Annual Report on Form 10-K for the year ended July 2, 2010, for further discussion of our purchase orders and purchase agreements and the associated dollar amounts. See Part II, Item 1A of this Quarterly Report on Form 10-Q for a discussion of the risks associated with these commitments.

Foreign Exchange Contracts— We purchase short-term, foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. See Part I, Item 3, of this Quarterly Report on Form 10-Q under the heading “Disclosure About Foreign Currency Risk,” for a description of our current foreign exchange contract commitments and Part I, Item 1, Note 8 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Indemnifications— In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of such agreements, products or services to be provided by us, or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of our officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers in certain circumstances.

It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements may not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements.

Unrecognized Tax Benefits— As of April 1, 2011, the cash portion of our total recorded liability for unrecognized tax benefits was $146 million. We estimate the timing of the future payments of these liabilities to be within the next one to five years. See Part I, Item 1, Note 6 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for information regarding our total tax liability for unrecognized tax benefits.

22

Stock Repurchase Program— Our Board of Directors previously authorized us to repurchase $750 million of our common stock in open market transactions under a stock repurchase program through March 31, 2013. Since the inception of this program in 2005 through April 1, 2011, we have repurchased 20 million shares of our common stock for a total cost of $334 million. We did not repurchase any shares under this program during the three months ended April 1, 2011. We repurchased 1.8 million shares for a total cost of $50 million during the nine months ended April 1, 2011. We may continue to repurchase our stock as we deem appropriate and market conditions allow. We expect stock repurchases to be funded principally by operating cash flows.

Critical Accounting Policies and Estimates

We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with U.S. GAAP. The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. We believe the following are our most critical accounting policies that affect significant areas and involve judgment and estimates made by us. If these estimates differ significantly from actual results, the impact to the consolidated financial statements may be material.

Revenue and Accounts Receivable

In accordance with standard industry practice, we provide distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and we provide resellers and OEMs with other sales incentive programs. At the time we recognize revenue to resellers and OEMs, we record a reduction of revenue for estimated price protection until the resellers sell such inventory to their customers and we also record a reduction of revenue for the other programs in effect. We base these adjustments on several factors including anticipated price decreases during the reseller holding period, resellers’ sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for hard drives or market conditions differ from our expectations, our operating results could be materially affected. We also have programs under which we reimburse qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product. Since the first quarter of fiscal 2010, total sales incentive and marketing programs have ranged from 7% to 12% of gross revenues per quarter. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue from the current range. Adjustments to revenues due to changes in accruals for these programs related to revenues reported in prior periods have averaged 0.2% of quarterly gross revenue since the first quarter of fiscal 2010.

We record an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, we routinely analyze the different receivable aging categories and establish reserves based on a combination of past due receivables and expected future losses based primarily on our historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if our overall loss history changes significantly, an adjustment in our allowance for doubtful accounts would be required, which could materially affect operating results.

We establish provisions against revenue and cost of revenue for sales returns in the same period that the related revenue is recognized. We base these provisions on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.

23

Warranty

We record an accrual for estimated warranty costs when revenue is recognized. We generally warrant our products for a period of one to five years. Our warranty provision considers estimated product failure rates and trends, estimated repair or replacement costs and estimated costs for customer compensatory claims related to product quality issues, if any. We use a statistical warranty tracking model to help prepare our estimates and assist us in exercising judgment in determining the underlying estimates. Our statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Our judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base our warranty estimates. We review our warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross margin and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from our estimates, our future results of operations could be materially affected. For a summary of historical changes in estimates related to pre-existing warranty provisions, refer to Part I, Item 1, Note 2 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Inventory

We value inventories at the lower of cost (first-in, first-out and weighted-average methods) or net realizable value. We use the first-in, first-out method to value the cost of the majority of our inventories, while we use the weighted-average method to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by us. We have determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, we relieve our precious metals inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted-average method of valuing precious metals does not materially differ from a first-in, first-out method. We record inventory write-downs for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.

We evaluate inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information, and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of our products, which may require a write down of inventory that could materially affect operating results.

Litigation and Other Contingencies

We disclose material contingencies deemed to be reasonably possible and accrue loss contingencies when, in consultation with our legal advisors, we conclude that a loss is probable and reasonably estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. Refer to Part I, Item 1, Note 5 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Income Taxes

We account for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities and expected benefits of utilizing net operating loss and tax credit carryforwards. We record a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each quarter we evaluate the need for a valuation allowance for our deferred tax assets and we adjust the valuation allowance so that we record net deferred tax assets only to the extent that we conclude it is more likely than not that these deferred tax assets will be realized.

We recognize liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in our provision for income taxes. The actual liability for unrealized tax benefit in any such contingency may be materially different from our estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously-recorded liabilities for unrealized tax benefits and materially affect our operating results.

24

Stock-based Compensation

We account for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options granted are estimated using a binomial model, and the fair values of all Employee Stock Purchase Plan (“ESPP”) purchase rights are estimated using the Black-Scholes-Merton option-pricing model. Both the binomial and the Black-Scholes-Merton models require the input of highly subjective assumptions. We are required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and our results of operations could be materially affected.

Recent Accounting Pronouncements

For a description of recently issued and adopted accounting pronouncements, including the respective dates of adoption and expected effects on our results of operations and financial condition, refer to Part I, Item I, Note 11 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, which is incorporated by reference in response to this item.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Disclosure About Foreign Currency Risk

Although the majority of our transactions are in U.S. dollars, some transactions are based in various foreign currencies. We purchase short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedge transactions is to minimize the impact of foreign currency fluctuations on our results of operations. The contract maturity dates do not exceed 12 months. We do not purchase foreign exchange contracts for trading purposes. Currently, we focus on hedging our foreign currency risk related to the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges. Thai Baht contracts are designated as either cash flow or fair value hedges. See Part I, Item 1, Note 8 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

As of April 1, 2011, we had outstanding the following purchased foreign exchange contracts (in millions, except weighted average contract rate):

	Contract		Weighted Average		Unrealized
	Amount		Contract Rate*		Gain
Foreign exchange contracts:
Thai Baht cash flow hedges	$	920		30.69	$	3
Thai Baht fair value hedges	$	60		30.27		—
Malaysian Ringgit cash flow hedges	$	266		3.14	$	5
Euro fair value hedges	$	11		0.71		—
British Pound Sterling fair value hedges	$	6		0.62		—

* Expressed in units of foreign currency per U.S. dollar.

During the three and nine month periods ended April 1, 2011, total net realized transaction and foreign exchange contract currency gains and losses were not material to the condensed consolidated financial statements.

25

Disclosure About Other Market Risks

Variable Interest Rate Risk

Borrowings under the term loan facility bear interest at a rate equal to, at the option of WDTI, either (a) a LIBOR rate determined by reference to the cost of funds for Eurodollar deposits for the interest period relevant to such borrowing, adjusted for certain additional costs (the “Eurocurrency Rate”) or (b) a base rate determined by reference to the higher of (i) the federal funds rate plus 0.50% and (ii) the prime rate as announced by JPMorgan Chase Bank, N.A. (the “Base Rate”); in each case plus an applicable margin. The applicable margin for borrowings under the term loan facility ranges from 1.25% to 1.50% with respect to borrowings at the Eurocurrency Rate and 0.0% to 0.125% with respect to borrowings at the Base Rate. The applicable margins for borrowings under the term loan facility are determined based upon a leverage ratio of the Company and its subsidiaries calculated on a consolidated basis. If the federal funds rate, prime rate or LIBOR rate increase, our interest payments could also increase. A one percent increase in the variable rate of interest on the term loan facility would increase interest expense by approximately $3 million annually.

Item 4. CONTROLS AND PROCEDURES

As required by SEC Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective. There has been no change in our internal control over financial reporting during the quarter ended April 1, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

For a description of our legal proceedings, refer to Part I, Item 1, Note 5 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, which is incorporated by reference in response to this item.

Item 1A. RISK FACTORS

We have updated a number of the risk factors affecting our business since those presented in our Annual Report on Form 10-K, Part I, Item 1A, for the fiscal year ended July 2, 2010. Except for the addition of the first five risk factors below and revisions to the sixth through ninth risk factors below, there have been no material changes in our assessment of our risk factors from those set forth in our Annual Report on Form 10-K for the fiscal year ended July 2, 2010. For convenience, all of our risk factors are included below.

The successful completion of our planned acquisition of HGST, and the integration of HGST’s business into our operations, is subject to risks and uncertainties, and in the event we fail in either endeavor our business may suffer.

We recently announced our planned acquisition of HGST. Our ability to complete the planned acquisition of HGST is subject to risks and uncertainties, including, but not limited to, the risk that a condition to closing of the transaction may not be satisfied and the risk that we fail to obtain the regulatory approvals and financing necessary to complete the transaction. These uncertainties regarding the acquisition may adversely affect our relationships with our vendors and customers, which could harm our operating results. In addition, in the event that the acquisition is not completed or is delayed, our business could suffer and the current market price of our common stock may decline.

26

The success of our planned acquisition of HGST will depend on our ability to realize the anticipated benefits from integrating HGST’s business into our operations. Due to legal restrictions, we and HGST have conducted, and until the completion of the planned acquisition will conduct, only limited planning regarding the integration of the two companies following the acquisition. Our ongoing business could be disrupted and our management’s attention diverted due to these integration planning activities and as a result of the actual integration of the two companies following the acquisition. Following the planned acquisition, we may fail to realize the anticipated benefits from this integration on a timely basis, or at all, for a variety of reasons, including the following:

• difficulties entering new markets or manufacturing in new geographies where we have no or limited direct prior experience;

• difficulties in coordinating geographically separate organizations, which may be subject to additional complications resulting from being geographically distant from our other operations;

• failure to identify or assess the magnitude of certain liabilities we are assuming in the acquisition, which could result in unexpected litigation or regulatory exposure, unfavorable accounting treatment, unexpected increases in taxes due, a loss of anticipated tax benefits or other adverse effects on our business, operating results or financial condition;

• failure to realize the anticipated increase in our revenues due to the acquisition if customers adjust their purchasing decisions and allocate more share to our competitors;

• difficulties or delays in incorporating acquired technologies or products with our existing product lines and maintaining uniform standards, controls, processes and policies;

• failure to successfully manage relationships with our combined supplier and customer base;

• the impact of the recent earthquakes, tsunami and related events in Japan on HGST’s business, component supply or Japan facilities;

• difficulties integrating and harmonizing business systems;

• difficulties in modifying HGST’s existing accounting and internal control systems to comply with Section 404 of the Sarbanes-Oxley Act of 2002, to which HGST is not currently subject, which could adversely impact the effectiveness of internal control over financial reporting for the combined company; and

• the loss of key employees.

If we are not able to successfully integrate HGST’s business and technology into our operations, the anticipated benefits and efficiencies of the planned acquisition may not be realized fully or at all, or may take longer to realize than expected, and our ability to compete, our revenue and gross margins and our results of operations may be adversely affected.

The integration of HGST may result in significant restructuring charges that could adversely affect the financial results of the combined company.

The financial results of the combined company may be adversely affected by cash expenses and non-cash accounting charges incurred in connection with the combination. The amount and timing of these possible charges are not yet known. The price of our common stock following the acquisition could decline to the extent the combined company’s financial results are materially affected by these charges.

The financing of our planned HGST acquisition will dilute our shareholders’ ownership interest in the company, and may have an adverse impact on our liquidity, limit our flexibility in responding to other business opportunities and increase our vulnerability to adverse economic and industry conditions.

Our planned acquisition of HGST will be financed by a combination of the issuance of additional shares of our common stock, the use of a significant amount of our cash on hand and the incurrence of a significant amount of indebtedness. The issuance of additional shares of our common stock will dilute your ownership interest in the company. The use of cash on hand and indebtedness to finance the acquisition will reduce our liquidity and could cause us to place more reliance on cash flow from operations to pay principal and interest on our debt, thereby reducing the availability of our cash flow for operations and development activities. The credit agreement we expect to enter into with respect to the indebtedness we will incur to finance the planned acquisition will contain restrictive covenants, including financial covenants requiring us to maintain specified financial ratios. Our ability to meet these restrictive covenants can be affected by events beyond our control. The indebtedness and these restrictive covenants will also have the effect, among other things, of impairing our ability to obtain additional financing, if needed, limiting our flexibility in the conduct of our business and making us more vulnerable to economic downturns and adverse competitive and industry conditions. In addition, a breach of the restrictive covenants could result in an event of default under the credit agreement we will enter into with respect to the indebtedness, which, if not cured or waived, could result in the indebtedness becoming immediately due and payable and could have a material adverse effect on our business, financial condition or operating results.

27

The regulatory approvals required in connection with our planned acquisition of HGST may not be obtained or may contain materially burdensome conditions.

Completion of our planned acquisition of HGST is conditioned upon the receipt of certain governmental approvals. Although we and HGST have agreed to take any and all actions to obtain the requisite governmental approvals in certain specified jurisdictions, unless such action would reasonably be expected to materially impair the business operations of the combined company absent such imposed condition, there can be no assurance that these approvals will be obtained. While we do not currently expect that any such conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of jeopardizing or delaying completion of the planned acquisition or reducing the anticipated benefits of the planned acquisition. If we agree to any material conditions in order to obtain any approvals required to complete the planned acquisition, the business and results of operations of the combined company may be adversely affected. On April 25, 2011, we and Hitachi received a request for additional information (a “second request”) from the U.S. Federal Trade Commission (the “FTC”) in connection with the FTC’s review of the Company’s planned acquisition of HGST. The second request extends the waiting period imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976 until 30 days after we and Hitachi have substantially complied with the second request unless the period is extended voluntarily by the parties or terminated sooner by the FTC.

Failure to complete the planned acquisition of HGST could negatively impact our stock price as well as our future business and financial results.

If the planned acquisition is not completed, our ongoing business may be adversely affected, and we will be subject to a number of risks, including the following:

• if the acquisition agreement is terminated by any party because the acquisition has not closed by March 7, 2012, and if, as of the time of such termination certain regulatory and antitrust closing conditions have not been satisfied due to the failure to receive any required antitrust or competition consent, approval or clearance or any action by any certain governmental entities to prevent the acquisition for antitrust or competition reasons, then we will be required to pay a termination fee of $250 million;

• we have incurred and will continue to incur costs relating to the planned acquisition (including significant legal and financial advisory fees) and many of these costs are payable by us whether or not the planned acquisition is completed; and

• matters relating to the planned acquisition (including integration planning) may require substantial commitments of time and resources by our management team, which could otherwise have been devoted to other opportunities that may have been beneficial to us;

in each case, without realizing any of the benefits of having completed the planned acquisition. If the planned acquisition is not completed, these risks may materialize and may adversely affect our business, financial results and stock price.

28

Our manufacturing operations, and those of certain of our suppliers and customers, are concentrated in large, purpose-built facilities, which subjects us to substantial risk of damage or loss if operations at any of these facilities are disrupted.

As a result of our cost structure and strategy of vertical integration, we conduct our manufacturing operations at large, high volume, purpose-built facilities. For example, approximately 80% of our requirement for heads is satisfied by wafers fabricated in our Fremont, California facility. Also, we manufacture the majority of our substrates for magnetic media in our Johor, Malaysia facility, and we finish a majority of our magnetic media in our facilities in Penang, Malaysia and Tuas, Singapore. A majority of our high volume hard drive manufacturing operations are conducted in our two facilities in Thailand, with the balance conducted in our Kuala Lumpur, Malaysia facility and the facilities of our contract manufacturers in Brazil, Europe and the United States. As part of our planned acquisition of HGST, we will also acquire manufacturing facilities located in Japan, China and the Philippines (as well as additional factories in Singapore, Thailand and Malaysia). The manufacturing facilities of many of our customers, our suppliers and our customers’ suppliers are also concentrated in certain geographic locations in Asia and elsewhere. A localized health risk affecting our employees at these facilities or the staff of our or our customers’ other suppliers, such as the spread of the Influenza A (H1N1) or a new pandemic influenza, could impair the total volume of hard drives that we are able to manufacture and/or sell, which would result in substantial harm to our operating results. Similarly, a fire, flood, earthquake, tsunami or other disaster, condition or event such as political instability, civil unrest or a power outage that adversely affects any of these facilities would significantly affect our ability to manufacture and/or sell hard drives, which would result in a substantial loss of sales and revenue and a substantial harm to our operating results.

For example, while we presently do not have manufacturing operations located in Japan, we do source certain components from suppliers with facilities in Japan. The recent earthquakes, tsunami and related events in Japan, including the resulting power outages, have affected and may continue to affect the supply of certain components used in the production of hard drives and systems that include hard drives. The development of events in Japan has, however, been fluid and unpredictable. If we experience any shortage of components of acceptable quality, or any interruption in the supply of required components we cannot promptly obtain from alternative sources at acceptable prices, our operating results would be adversely affected. In addition, even if the events in Japan do not adversely affect our component supply, they may adversely affect the supply of other components our customers use in their systems, which could negatively impact demand for our products and, therefore, our revenues.

Shortages of commodity materials or commodity components, price volatility, or use by other industries of materials and components used in the hard drive industry, may negatively impact our operating results.

Increases in the cost for certain commodity materials or commodity components may increase our costs of manufacturing and transporting hard drives and key components. Shortages of commodity components such as DRAM and NAND flash, or commodity materials such as glass substrates, stainless steel, aluminum, nickel, neodymium, ruthenium, platinum or cerium, may increase our costs and may result in lower operating margins if we are unable to find ways to mitigate these increased costs. We or our suppliers acquire certain precious metals and rare earth metals like ruthenium, platinum, neodymium and cerium, critical to the manufacture of components in our products from a number of countries, including the People’s Republic of China. The government of China or any other nation may impose regulations, quotas or embargoes upon these metals that would restrict the worldwide supply of such metals and/or increase their cost, both of which could negatively impact our operating results until alternative suppliers are sourced. Furthermore, if other high volume industries increase their demand for materials or components such as these, our costs may further increase, which could have an adverse effect on our operating margins. In addition, shortages in other commodity components and materials used in our customers’ products could result in a decrease in demand for our products, which would negatively impact our operating results. The volatility in the cost of oil also affects our costs and may result in lower operating margins if we are unable to pass these increased costs on to our customers.

The difficulty of introducing hard drives with higher levels of areal density and the challenges of reducing other costs may impact our ability to achieve historical levels of cost reduction.

Storage capacity of the hard drive, as manufactured by us, is determined by the number of disks and each disk’s areal density. Areal density is a measure of the amount of magnetic bits that can be stored on the recording surface of the disk. Generally, the higher the areal density, the more information can be stored on a single platter. Historically, we have been able to achieve a large percentage of cost reduction through increases in areal density. Increases in areal density mean that the average drive we sell has fewer heads and disks for the same capacity and, therefore, may result in a lower component cost. However, increasing areal density has become more difficult in the hard drive industry. If we are not able to increase areal density at the same rate as our competitors or at a rate that is expected by our customers, we may be required to include more components in our drives to meet demand without corresponding incremental revenue, which could negatively impact our operating margins and make achieving historical levels of cost reduction difficult or unlikely. Additionally, increases in areal density may require us to make further capital expenditures on items such as new testing equipment needed as a result of an increased number of GB per platter. Our inability to achieve cost reductions could adversely affect our operating results.

29

If we fail to anticipate or timely respond to changes in the markets for hard drives, our operating results could be adversely affected.

The PC industry, which comprises a substantial portion of our revenue, is experiencing a shift in demand from 3.5-inch to 2.5-inch form factor disk drives. As a result, the market for 2.5-inch form factor drives is becoming increasingly dominated by large brand OEM customers. These OEM customers may be able to command increased leverage in negotiating prices and other terms of sale. If we are not successful in responding to these changes in the market for smaller form factor drives, our business may suffer.

In addition, during past economic downturns, as well as over the past few years, the consumer market for computers has shifted significantly towards lower priced systems, and we therefore expect this trend to continue in light of current global economic conditions. If we are not able to continue to offer a competitively priced hard drive for the low-cost PC market, our share of that market will likely fall, which could harm our operating results.

The market for hard drives is also fragmenting into a variety of devices and products. Many industry analysts expect, as do we, that as content increasingly converts to digital technology from the older analog technology, the technology of computers and consumer electronics will continue to converge, and hard drives may be found in many products other than computers, such as various CE devices. However, there has also been a recent rapid growth in CE devices that do not contain a hard drive such as tablet computers and smartphones. While tablet computers and smartphones provide many of the same capabilities as PCs, the extent to which they will displace or materially affect the demand for PCs is uncertain. If device-makers are successful in achieving customer acceptance of these devices as a replacement for traditional computing applications that contain hard drives, or if we are not successful in adapting our product offerings to include alternative storage solutions that address these devices, then demand for our products may decrease, which could adversely affect our operating results.

In addition, consumers traditionally have stored their data on their PC, often supplemented with personal external storage devices. Most businesses also include similar local storage as a primary or secondary storage location. This storage is typically provided by hard disk drives. Recently, cloud computing has emerged whereby applications and data are hosted, accessed and processed through a third-party provider over a broadband Internet connection, potentially reducing or eliminating the need for, among other things, significant storage inside the accessing computer. This trend could cause the market for disk drives in computers to decline over time, which could harm our business to the extent this decline is not offset by the sale of our products to customers who provide cloud computing services.

Moreover, some devices such as personal video recorders and digital video recorders, or some new PC operating systems which allow greater consumer choice in levels of functionality and therefore greater market differentiation, may require attributes not currently offered in our products, resulting in a need to develop new interfaces, form factors, technical specifications or product features, increasing our overall operational expense without corresponding incremental revenue at this stage. If we are not successful in continuing to deploy our hard drive technology and expertise to develop new products for emerging markets such as the CE market, or if we are required to incur significant costs in developing such products, it may harm our operating results.

Negative or uncertain global economic conditions could result in a decrease in our sales and revenue and an increase in our operating costs, which could adversely affect our business and operating results.

Negative or uncertain global economic conditions could cause many of our direct and indirect customers to delay or reduce their purchases of our products and systems containing our products. In addition, many of our customers in each of the OEM, distribution and retail channels rely on credit financing in order to purchase our products. If negative conditions in the global credit markets prevent our customers’ access to credit, product orders in these channels may decrease, which could result in lower revenue. Likewise, if our suppliers face challenges in obtaining credit, in selling their products or otherwise in operating their businesses, they may be unable to offer the materials we use to manufacture our products. These actions could result in reductions in our revenue, increased price competition and increased operating costs, which could adversely affect our business, results of operations and financial condition.

30

If industry demand slows significantly as a result of negative or uncertain global economic conditions or otherwise, we may have to take steps to align our cost structure with demand, which could result in impairment charges and have a negative impact on our operating results.

If demand slows significantly as a result of a deterioration in economic conditions or otherwise, we may need to execute restructuring activities to realign our cost structure with softening demand. The occurrence of restructuring activities could result in impairment charges and other expenses, which could adversely impact our results of operations or financial condition.

Negative or uncertain global economic conditions increase the risk that we could suffer unrecoverable losses on our customers’ accounts receivable, which would adversely affect our financial results.

We extend credit and payment terms to some of our customers. In addition to ongoing credit evaluations of our customers’ financial condition, we traditionally seek to mitigate our credit risk by purchasing credit insurance on certain of our accounts receivable balances; however, as a result of the continued uncertainty and volatility in global economic conditions, we may find it increasingly difficult to be able to insure these accounts receivable. We could suffer significant losses if a customer whose accounts receivable we have not insured, or have underinsured, fails and is unable to pay us. Additionally, negative or uncertain global economic conditions increase the risk that if a customer whose accounts receivable we have insured fails, the financial condition of the insurance carrier for such customer account may have also deteriorated such that it cannot cover our loss. A significant loss of an accounts receivable that we cannot recover through credit insurance would have a negative impact on our financial results.

If our long-lived assets or goodwill become impaired, it may adversely affect our operating results.

Negative or uncertain global economic conditions could result in circumstances, such as a sustained decline in our stock price and market capitalization or a decrease in our forecasted cash flows such that they are insufficient, indicating that the carrying value of our long-lived assets or goodwill may be impaired. If we are required to record a significant charge to earnings in our consolidated financial statements because an impairment of our long-lived assets or goodwill is determined, our results of operations will be adversely affected.

Declines in average selling prices (“ASPs”) in the hard drive industry could adversely affect our operating results.

Historically, the hard drive industry has experienced declining ASPs. Our ASPs tend to decline when competitors lower prices as a result of decreased costs or to absorb excess capacity, liquidate excess inventories, restructure or attempt to gain market share. Our ASPs also decline when there is a shift in the mix of product sales, and sales of lower priced products increase relative to those of higher priced products. When ASPs in the hard drive industry decline, our ASPs are also likely to decline, which adversely affects our operating results.

Our prices and margins are subject to declines due to unpredictable end-user demand and oversupply of hard drives.

Demand for our hard drives depends on the demand for systems manufactured by our customers and on storage upgrades to existing systems. The demand for systems has been volatile in the past and often has had an exaggerated effect on the demand for hard drives in any given period. As a result, the hard drive market has experienced periods of excess capacity, which can lead to liquidation of excess inventories and intense price competition. If intense price competition occurs, we may be forced to lower prices sooner and more than expected, which could result in lower revenue and gross margins.

Our failure to accurately forecast market and customer demand for our products could adversely affect our business and financial results or operating efficiencies.

The data storage industry faces difficulties in accurately forecasting market and customer demand for its products. Accurately forecasting demand has become increasingly difficult for us, our customers and our suppliers in light of the volatility in global economic conditions. In addition, because hard drives are designed to be largely substitutable, our demand forecasts may be impacted significantly by the strategic actions of our competitors. The variety and volume of products we manufacture is based in part on these forecasts. If our forecasts exceed actual market demand, or if market demand decreases significantly from our forecasts, then we could experience periods of product oversupply and price decreases, which could impact our financial performance. If our forecasts do not meet actual market demand, or if market demand increases significantly beyond our forecasts or beyond our ability to add manufacturing capacity, then we may not be able to satisfy customer product needs, which could result in a loss of market share if our competitors are able to meet customer demands.

31

Although we receive forecasts from our customers, they are not generally obligated to purchase the forecasted amounts. Sales volumes in the distribution and retail channels are volatile and harder to predict than sales to our OEM or ODM customers. We consider these forecasts in determining our component needs and our inventory requirements. If we fail to accurately forecast our customers’ product demands, we may have inadequate or excess inventory of our products or components, which could adversely affect our operating results.

In order to efficiently and timely meet the demands of many of our OEM customers, we position our products in multiple strategic locations based on the amounts forecasted by such customers. If an OEM customer’s actual product demands decrease significantly from its forecast, then we may incur additional costs in relocating the products that have not been purchased by the OEM. This could result in a delay in our product sales and an increase in our operating costs, which may negatively impact our operating results.

Our entry into additional storage markets increases the complexity of our business, and if we are unable to successfully adapt our business processes as required by these new markets, we will be at a competitive disadvantage and our ability to grow will be adversely affected.

As we expand our product line to sell into additional storage markets, the overall complexity of our business increases at an accelerated rate and we must make necessary adaptations to our business model to address these complexities. For example, as we have previously disclosed, we entered the traditional enterprise market in November 2009. In addition to requiring significant capital expenditures, our entry into the traditional enterprise market adds complexity to our business that requires us to effectively adapt our business and management processes to address the unique challenges and different requirements of the traditional enterprise market, while maintaining a competitive operating cost model. If we fail to gain market acceptance in the traditional enterprise storage market, we will remain at a competitive disadvantage to the companies that succeed in this market and our ability to continue our growth will be negatively affected.

Our customers’ demand for storage capacity may not continue to grow at current industry estimates, which may lower the prices our customers are willing to pay for our products or put us at a disadvantage to competing technologies.

Our customers’ demand for storage capacity may not continue to grow at current industry estimates as a result of developments in the regulation and enforcement of digital rights management, the emergence of processes such as cloud computing, data deduplication and storage virtualization, economic conditions or otherwise. In addition, the rate of increase in areal density may be greater than the increase in our customers’ demand for storage capacity. These factors could lead to our customers’ storage capacity needs being satisfied at lower prices with lower capacity hard drives or solid-state storage products that we do not offer, thereby decreasing our revenue or putting us at a disadvantage to competing storage technologies. As a result, even with increasing aggregate demand for storage capacity, our ASPs could decline, which could adversely affect our operating results.

Expansion into new hard drive markets may cause our capital expenditures to increase, and if we do not successfully expand into new markets, our business may suffer.

To remain a significant supplier of hard drives, we will need to offer a broad range of hard drive products to our customers. We currently offer a variety of 3.5-inch or 2.5-inch hard drives for the desktop, mobile, enterprise, CE and external storage markets. However, demand for hard drives may shift to products in form factors or with interfaces that our competitors offer but which we do not. Expansion into other hard drive markets and resulting increases in manufacturing capacity requirements may require us to make substantial additional investments in part because our operations are largely vertically integrated now that we manufacture heads and magnetic media for use in many of the hard drives we manufacture. If we fail to successfully expand into new hard drive markets with products that we do not currently offer, we may lose business to our competitors who offer these products.

32

If we fail to successfully manage our new product development or new market expansion, or if we fail to anticipate the issues associated with such development or expansion, our business may suffer.

While we continue to develop new products and look to expand into new markets, the success of our new product introductions depends on a number of factors, including our ability to anticipate and manage a variety of issues associated with these new products and new markets, such as:

• difficulties faced in manufacturing ramp;

• market acceptance;

• effective management of inventory levels in line with anticipated product demand; and

• quality problems or other defects in the early stages of new product introduction that were not anticipated in the design of those products.

Further, we need to identify how any of the new markets into which we are expanding may have different characteristics from the markets in which we currently exist and properly address these differences. These characteristics may include:

• demand volume requirements;

• demand seasonality;

• product generation development rates;

• customer concentrations;

• warranty expectations and product return policies; and

• cost, performance and compatibility requirements.

Our business may suffer if we fail to successfully anticipate and manage these issues associated with our product development and market expansion. For example, our branded products are designed to attach to and interoperate with a wide variety of PC and CE devices, and therefore their functionality relies on the manufacturer of such devices, or the associated operating systems, enabling the manufacturer’s devices to operate with our branded products. If our branded products are not compatible with a wide variety of devices, or if device manufacturers design their devices so that our branded products cannot operate with them, and we cannot quickly and efficiently adapt our branded products to address these compatibility issues, our business could suffer.

Expanding into new markets exposes our business to different seasonal demand cycles, which in turn could adversely affect our operating results.

The CE and retail markets have different seasonal pricing and volume demand cycles as compared to the PC market. By expanding into these markets, we became exposed to seasonal fluctuations that are different from, and in addition to, those of the PC market. For example, because the primary customer for our branded products are individual consumers, this market has historically experienced a dramatic increase in demand during the winter holiday season. If we do not properly adjust our supply to these new demand cycles, we risk having excess inventory during periods of low demand and insufficient inventory during periods of high demand, which could adversely affect our operating results.

Selling to the retail market is an important part of our business, and if consumer spending decreases, or if we fail to maintain and grow our market share or gain market acceptance of our branded products, our operating results could suffer.

Selling branded products is an important part of our business, and as our branded products revenue increases as a portion of our overall revenue, our success in the retail market becomes increasingly important to our operating results. If consumer spending decreases as a result of the recent uncertainty and volatility in global economic conditions or otherwise, our operating results could suffer because of the increased importance of our branded products business.

33

We sell our branded products directly to a select group of major retailers, such as computer superstores and CE stores, and authorize sales through distributors to other retailers and online resellers. Our current retail customer base is primarily in the United States, Canada and Europe. We are facing increased competition from other companies for shelf space at a small number of major retailers that have strong buying power and pricing leverage. Some of our competitors in the branded product market are large, diversified companies with well-established brands. If we are unable to maintain effective working relationships with major retailers and online resellers, or if we fail to successfully expand into and gain market acceptance of our products in multiple channels, our competitive position in the branded product market may suffer and our operating results may be adversely affected.

Our success in the retail market also depends on our ability to maintain our brand image and corporate reputation. Adverse publicity, whether or not justified, or allegations of product quality issues, even if false or unfounded, could tarnish our reputation and cause our customers to choose products offered by our competitors. In addition, the proliferation of new methods of mass communication facilitated by the Internet makes it easier for false or unfounded allegations to adversely affect our brand image and reputation. If customers no longer maintain a preference for WD^®-brand products, our operating results may be adversely affected.

Additionally, we face strong competition in maintaining and trying to grow our market share in the retail market, particularly because of the relatively low barriers to entry in this market. For example, several additional hard drive manufacturers have recently disclosed plans to expand into the external storage market. As these companies attempt to gain market share, we may have difficulty in maintaining or growing our market share and there may be increased downward pressure on pricing. There can be no assurance that any new products we introduce into the retail market will gain market acceptance, and if they do not, our operating results could suffer.

Loss of market share with or by a key customer, or consolidation among our customer base, could harm our operating results.

During the quarter ended April 1, 2011, a large percentage of our revenue, 49%, came from sales to our top 10 customers. These customers have a variety of suppliers to choose from and therefore can make substantial demands on us, including demands on product pricing and on contractual terms, which often results in the allocation of risk to us as the supplier. Even if we successfully qualify a product with a customer, the customer is not generally obligated to purchase any minimum volume of products from us and may be able to cancel an order or terminate its relationship with us at any time. Our ability to maintain strong relationships with our principal customers is essential to our future performance. If we lose a key customer, if any of our key customers reduce their orders of our products or require us to reduce our prices before we are able to reduce costs, if a customer is acquired by one of our competitors or if a key customer suffers financial hardship, our operating results would likely be harmed.

Additionally, if there is consolidation among our customer base, our customers may be able to command increased leverage in negotiating prices and other terms of sale, which could adversely affect our profitability. In addition, if, as a result of increased leverage, customer pressures require us to reduce our pricing such that our gross margins are diminished, we could decide not to sell our products to a particular customer, which could result in a decrease in our revenue. Consolidation among our customer base may also lead to reduced demand for our products, replacement of our products by the combined entity with those of our competitors and cancellations of orders, each of which could harm our operating results.

Current or future competitors may gain a technology advantage or develop an advantageous cost structure that we cannot match.

It may be possible for our current or future competitors to gain an advantage in product technology, manufacturing technology, or process technology, which may allow them to offer products or services that have a significant advantage over the products and services that we offer. Advantages could be in capacity, performance, reliability, serviceability, or other attributes. We may be at a competitive disadvantage to any companies that are able to gain these advantages.

Further industry consolidation could provide competitive advantages to our competitors.

The hard drive industry has experienced consolidation over the past several years. Consolidation by our competitors may enhance their capacity, abilities and resources and lower their cost structure, causing us to be at a competitive disadvantage. Additionally, continued industry consolidation may lead to uncertainty in areas such as component availability, which could negatively impact our cost structure.

34

Sales in the distribution channel are important to our business, and if we fail to maintain brand preference with our distributors or if distribution markets for hard drives weaken, our operating results could suffer.

Our distribution customers typically sell to small computer manufacturers, dealers, systems integrators and other resellers. We face significant competition in this channel as a result of limited product qualification programs and a significant focus on price and availability of product. If we fail to remain competitive in terms of our technology, quality, service and support, our distribution customers may favor our competitors, and our operating results could suffer. Additionally, if the distribution market weakens as a result of a slowing PC growth rate, technology transitions or a significant change in consumer buying preference, or if we experience significant price declines due to oversupply in the distribution channel, then our operating results would be adversely affected.

The hard drive industry is highly competitive and can be characterized by significant shifts in market share among the major competitors.

The price of hard drives has fallen over time due to increases in supply, cost reductions, technological advances and price reductions by competitors seeking to liquidate excess inventories or attempting to gain market share. In addition, rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence. These factors, taken together, may result in significant shifts in market share among the industry’s major participants. In addition, product recalls can lead to a loss of market share, which could adversely affect our operating results.

Some of our competitors with diversified business units outside the hard drive industry may over extended periods of time sell hard drives at prices that we cannot profitably match.

Some of our competitors earn a significant portion of their revenue from business units outside the hard drive industry. Because they do not depend solely on sales of hard drives to achieve profitability, they may sell hard drives at lower prices and operate their hard drive business unit at a loss over an extended period of time while still remaining profitable overall. In addition, if these competitors can increase sales of non-hard drive products to the same customers, they may benefit from selling their hard drives at lower prices. Our operating results may be adversely affected if we cannot successfully compete with the pricing by these companies.

If we fail to qualify our products with our customers or if product life cycles lengthen, it may have a significant adverse impact on our sales and margins.

We regularly engage in new product qualification with our customers. Once a product is accepted for qualification testing, failures or delays in the qualification process can result in delayed or reduced product sales, reduced product margins caused by having to continue to offer a more costly current generation product, or lost sales to that customer until the next generation of products is introduced. The effect of missing a product qualification opportunity is magnified by the limited number of high volume OEMs, which continue to consolidate their share of the storage markets. Likewise, if product life cycles lengthen, we may have a significantly longer period to wait before we have an opportunity to qualify a new product with a customer, which could reduce our profits because we expect declining gross margins on our current generation products as a result of competitive pressures.

We are subject to risks related to product defects, which could result in product recalls or epidemic failures and could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated.

We warrant the majority of our products for periods of one to five years. We test our hard drives in our manufacturing facilities through a variety of means. However, there can be no assurance that our testing will reveal defects in our products, which may not become apparent until after the products have been sold into the market. Accordingly, there is a risk that product defects will occur, which could require a product recall. Product recalls can be expensive to implement and, if a product recall occurs during the product’s warranty period, we may be required to replace the defective product. Moreover, there is a risk that product defects may trigger an epidemic failure clause in a customer agreement. If an epidemic failure occurs, we may be required to replace or refund the value of the defective product and to cover certain other costs associated with the consequences of the epidemic failure. In addition, a product recall or epidemic failure may damage our reputation or customer relationships, and may cause us to lose market share with our customers, including our OEM and ODM customers.

35

Our standard warranties contain limits on damages and exclusions of liability for consequential damages and for misuse, improper installation, alteration, accident or mishandling while in the possession of someone other than us. We record an accrual for estimated warranty costs at the time revenue is recognized. We may incur additional operating expenses if our warranty provision does not reflect the actual cost of resolving issues related to defects in our products, whether as a result of a product recall, epidemic failure or otherwise. If these additional expenses are significant, it could adversely affect our business, financial condition and operating results.

A competitive cost structure is critical to our operating results, and increased costs may adversely affect our operating margin.

A competitive cost structure for our products, including critical components, labor and overhead, is critical to the success of our business, and our operating results depend on our ability to maintain competitive cost structures on new and established products. If our competitors are able to achieve a lower cost structure that we are unable to match, we could be at a competitive disadvantage to those competitors.

If we fail to maintain effective relationships with our major component suppliers, our supply of critical components may be at risk and our profitability could suffer.

While we make most of our own heads and magnetic media for some of our product families, we do, according to our sourcing strategy, purchase some percentage of our required heads and magnetic media from our external supply base. In addition, we purchase a majority of our other components, including all mechanical and electronic components, from our external supply base. For certain components, we use multiple suppliers that deploy different technology or processes, and we must successfully integrate components from these suppliers in our products. Accordingly, we must maintain effective relationships with our supply base to source our component needs, develop compatible technology, and maintain continuity of supply at reasonable costs. If we fail to maintain effective relationships with our supply base, or if we fail to integrate components from our suppliers effectively, this may adversely affect our ability to develop and deliver the best products to our customers and our profitability could suffer. For example, in August 2003, we settled litigation with a supplier who previously was the sole source of read channel devices for our hard drives. As a result of the disputes that gave rise to the litigation, our profitability was at risk until another supplier’s read channel devices could be designed into our products. Similar disputes with other strategic component suppliers could adversely affect our operating results.

Violation of applicable laws, including labor or environmental laws, and certain other practices by our suppliers could harm our business.

We expect our suppliers, sub-suppliers and sub-contractors (collectively referred to as “suppliers”) to operate in compliance with applicable laws and regulations, including labor and environmental laws, and to otherwise meet our required supplier standards of conduct. While our internal operating guidelines promote ethical business practices, we do not control our suppliers or their labor or environmental practices. The violation of labor, environmental or other laws by any of our suppliers, or divergence of a supplier’s business practices from those generally accepted as ethical in the United States, could harm our business by:

• interrupting or otherwise disrupting the shipment of our product components;

• damaging our reputation;

• forcing us to find alternate component sources;

• reducing demand for our products (for example, through a consumer boycott); or

• exposing us to potential liability for our supplier’s wrongdoings.

36

Dependence on a limited number of qualified suppliers of components and manufacturing equipment could lead to delays, lost revenue or increased costs.

Our future operating results may depend substantially on our suppliers’ ability to timely qualify their components in our programs, and their ability to supply us with these components in sufficient volumes to meet our production requirements. A number of the components that we use are available from only a single or limited number of qualified suppliers, and may be used across multiple product lines. In addition, some of the components (or component types) used in our products are used in other devices, such as mobile telephones and digital cameras. If there is a significant simultaneous upswing in demand for such a component (or component type) from several high volume industries resulting in a supply reduction, if a component is otherwise in short supply, or if a supplier fails to qualify or has a quality issue with a component, we may experience delays or increased costs in obtaining that component. If we are unable to obtain sufficient quantities of materials used in the manufacture of magnetic components, or other necessary components, we may experience production delays, which could cause us loss of revenue. If a component becomes unavailable, we could suffer significant loss of revenue.

In addition, certain equipment and consumables we use in our manufacturing or testing processes are available only from a limited number of suppliers. Some of this equipment and consumables use materials that at times could be in short supply. If these materials are not available, or are not available in the quantities we require for our manufacturing and testing processes, our ability to manufacture our products could be impacted, and we could suffer significant loss of revenue.

Each of the following could also significantly harm our operating results:

• an unwillingness of a supplier to supply such components or equipment to us;

• consolidation of key suppliers;

• failure of a key supplier’s business process;

• a key supplier’s or sub-supplier’s inability to access credit necessary to operate its business; or

• failure of a key supplier to remain in business, to remain an independent merchant supplier, or to adjust to market conditions.

Contractual commitments with component suppliers may result in us paying increased charges and cash advances for such components or may cause us to have inadequate or excess component inventory.

To reduce the risk of component shortages, we attempt to provide significant lead times when buying components, which may subject us to cancellation charges if we cancel orders as a result of technology transitions or changes in our component needs. In addition, we may from time to time enter into contractual commitments with component suppliers in an effort to increase and stabilize the supply of those components and enable us to purchase such components at favorable prices. Some of these commitments may require us to buy a substantial number of components from the supplier or make significant cash advances to the supplier; however, these commitments may not result in a satisfactory increase or stabilization of the supply of such components. Furthermore, as a result of current global economic conditions, our ability to forecast our requirements for these components has become increasingly difficult, therefore increasing the risk that our contractual commitments may not meet our actual supply requirements, which could cause us to have inadequate or excess component inventory and adversely affect our operating results and increase our operating costs.

Failure by certain suppliers to effectively and efficiently develop and manufacture components, technology or production equipment for our products may adversely affect our operations.

We rely on suppliers for various component parts that we integrate into our hard drives but do not manufacture ourselves, such as semiconductors, motors, flex circuits and suspensions. Likewise, we rely on suppliers for certain technology and equipment necessary for advanced development technology for future products. Some of these components, and most of this technology and production equipment, must be specifically designed to be compatible for use in our products or for developing and manufacturing our future products, and are only available from a limited number of suppliers, some of with whom we are sole sourced. We are therefore dependent on these suppliers to be able and willing to dedicate adequate engineering resources to develop components that can be successfully integrated with our products, and technology and production equipment that can be used to develop and manufacture our next-generation products efficiently. The failure of these suppliers to effectively and efficiently develop and manufacture components that can be integrated into our products or technology and production equipment that can be used to develop or manufacture next generation products may cause us to experience inability or delay in our manufacturing and shipment of hard drive products, our expansion into new technology and markets, or our ability to remain competitive with alternative storage technologies, therefore adversely affecting our business and financial results.

37

There are certain additional capital expenditure costs and asset utilization risks to our business associated with our strategy to vertically integrate our operations.

Our vertical integration of head and magnetic media manufacturing resulted in a fundamental change in our operating structure, as we now manufacture heads and magnetic media for use in many of the hard drives we manufacture. Consequently, we make more capital investments and carry a higher percentage of fixed costs than we would if we were not vertically integrated. If the overall level of production decreases for any reason, and we are unable to reduce our fixed costs to match sales, our head or magnetic media manufacturing assets may face under-utilization that may impact our operating results. We are therefore subject to additional risks related to overall asset utilization, including the need to operate at high levels of utilization to drive competitive costs and the need for assured supply of components that we do not manufacture ourselves.

In addition, we may incur additional risks, including:

• failure to continue to leverage the integration of our magnetic media technology with our head technology;

• insufficient third party sources to satisfy our needs if we are unable to manufacture a sufficient supply of heads or magnetic media;

• third party head or magnetic media suppliers may not continue to do business with us or may not do business with us on the same terms and conditions we have previously enjoyed;

• claims that our manufacturing of heads or magnetic media may infringe certain intellectual property rights of other companies; and

• difficulties locating in a timely manner suitable manufacturing equipment for our head or magnetic media manufacturing processes and replacement parts for such equipment.

If we do not adequately address the challenges related to our head or magnetic media manufacturing operations, our ongoing operations could be disrupted, resulting in a decrease in our revenue or profit margins and negatively impacting our operating results.

If we are unable to timely and cost-effectively develop heads and magnetic media with leading technology and overall quality, our ability to sell our products may be significantly diminished, which could materially and adversely affect our business and financial results.

Under our business plan, we are developing and manufacturing a substantial portion of the heads and magnetic media used in the hard drive products we manufacture. Consequently, we are more dependent upon our own development and execution efforts and less able to take advantage of head and magnetic media technologies developed by other manufacturers. Technology transition for head and magnetic media designs is critical to increasing our volume production of heads and magnetic media. There can be no assurance, however, that we will be successful in timely and cost-effectively developing and manufacturing heads or magnetic media for products using future technologies. We also may not effectively transition our head or magnetic media design and technology to achieve acceptable manufacturing yields using the technologies necessary to satisfy our customers’ product needs, or we may encounter quality problems with the heads or magnetic media we manufacture. In addition, we may not have access to external sources of supply without incurring substantial costs which would negatively impact our business and financial results.

Changes in product life cycles could adversely affect our financial results.

If product life cycles lengthen, we may need to develop new technologies or programs to reduce our costs on any particular product to maintain competitive pricing for that product. If product life cycles shorten, it may result in an increase in our overall expenses and a decrease in our gross margins, both of which could adversely affect our operating results. In addition, shortening of product life cycles also makes it more difficult to recover the cost of product development before the product becomes obsolete. Our failure to recover the cost of product development in the future could adversely affect our operating results.

38

If we fail to make the technical innovations necessary to continue to increase areal density, we may fail to remain competitive.

New products in the hard drive market typically require higher areal densities than previous product generations, posing formidable technical and manufacturing challenges. Higher areal densities require existing head and magnetic media technology to be improved or new technologies developed to accommodate more data on a single disk. In addition, our introduction of new products during a technology transition increases the likelihood of unexpected quality concerns. Our failure to bring high quality new products to market on time and at acceptable costs may put us at a competitive disadvantage to companies that achieve these results.

We make significant investments in research and development, and unsuccessful investments could materially adversely affect our business, financial condition and results of operations.

Over the past several years, our business strategy has been to derive a competitive advantage by moving from being a follower of new technologies to being a leader in the innovation and development of new technologies. This strategy requires us to make significant investments in research and development. There can be no assurance that these investments will result in viable technologies or products, or if these investments do result in viable technologies or products, that they will be profitable or accepted by the market. Significant investments in unsuccessful research and development efforts could materially adversely affect our business, financial condition and results of operations.

A fundamental change in recording technology could result in significant increases in our operating expenses and could put us at a competitive disadvantage.

Historically, when the industry experiences a fundamental change in technology, any manufacturer that fails to successfully and timely adjust its designs and processes to accommodate the new technology fails to remain competitive. There are some revolutionary technologies, such as current-perpendicular-to-plane giant magnetoresistance, shingle magnetic recording, energy assisted magnetic recording, patterned magnetic media and advanced signal processing, that if implemented by a competitor on a commercially viable basis ahead of the industry, could put us at a competitive disadvantage. As a result of these technology shifts, we could incur substantial costs in developing new technologies, such as heads, magnetic media, and tools to remain competitive. If we fail to successfully implement these new technologies, or if we are significantly slower than our competitors at implementing new technologies, we may not be able to offer products with capacities that our customers desire. For example, new recording technology requires changes in the manufacturing process of heads and magnetic media, which may cause longer production times and reduce the overall availability of magnetic media in the industry. Additionally, the new technology requires a greater degree of integration between heads and magnetic media which may lengthen our time of development of hard drives using this technology.

Furthermore, as we attempt to develop and implement new technologies, we may become more dependent on suppliers to ensure our access to components, technology and production equipment that accommodate the new technology. For example, advanced wafer and magnetic media manufacturing technologies have historically been developed for use in the semiconductor industry prior to the hard drive industry. However, successful implementation of the use of patterned magnetic media with hard drive magnetic media currently presents a significant technical challenge facing the hard drive industry but not the semiconductor industry. Therefore, our suppliers may not be willing to dedicate adequate engineering resources to develop manufacturing equipment for patterned magnetic media prior to a need for the equipment in the semiconductor industry. We believe that if new technologies, such as energy assisted magnetic recording, are not successfully implemented in the hard drive industry, then alternative storage technologies like solid-state storage may more rapidly overtake hard drives as the preferred storage solution for higher capacity storage needs. This result would put us at a competitive disadvantage and negatively impact our operating results.

39

If we do not properly manage the technology transitions of our products, our competitiveness and operating results may be negatively affected.

The storage markets in which we offer our products continuously undergo technology transitions which we must anticipate and adapt our products to address in a timely manner. For example, serial interfaces normally go through cycles in which their maximum speeds double. We must effectively manage the transition of the features of our products to address these faster interface speeds in a timely manner in order to remain competitive and cost effective. If we fail to successfully and timely manage the transition to faster interface speeds, we may be at a competitive disadvantage to other companies that have successfully adapted their products in a timely manner and our operating results may suffer.

If we fail to develop and introduce new hard drives that are competitive against alternative storage technologies, our business may suffer.

Our success depends in part on our ability to develop and introduce new products in a timely manner in order to keep pace with competing technologies. Alternative storage technologies like solid-state storage technology have successfully served digital entertainment markets for products such as digital cameras, MP3 players, USB flash drives, mobile phones and tablet devices that require a relatively low amount of storage capacity that cannot be economically serviced using hard drive technology. Typically, storage needs for higher capacity and performance, with lower cost-per-gigabyte, have been better served by hard drives. However, advances in semiconductor technology have resulted in solid-state storage emerging as a technology that is competitive with hard drives for niche high performance needs in advanced digital computing markets such as enterprise servers and storage, in spite of the associated challenges in the attributes of cost, capacity and reliability. Solid-state storage is produced by large semiconductor companies who can then sell their storage products at lower prices while still remaining profitable overall. This can help them improve their market share at the expense of the competition. In addition, these semiconductor companies may choose to supply companies like us with semiconductor media at prices that make it difficult, if not impossible, for us to compete with them on a profitable basis. As a result, there can be no assurance that we will be successful in anticipating and developing new products for the desktop, mobile, enterprise, CE and external storage markets in response to solid-state storage, as well as other competing technologies. If our hard drive technology fails to offer higher capacity, performance and reliability with lower cost-per-gigabyte than solid-state storage for the desktop, mobile, enterprise, CE and external storage markets, we will be at a competitive disadvantage to companies using semiconductor technology to serve these markets and our business will suffer.

Spending to improve our technology and develop new technology to remain competitive may negatively impact our financial results.

In attempting to remain competitive, we may need to increase our capital expenditures and expenses above our historical run-rate model in order to attempt to improve our existing technology and develop new technology. Increased investments in technology could cause our cost structure to fall out of alignment with demand for our products which would have a negative impact on our financial results.

Our operating results will be adversely affected if we fail to optimize the overall quality, time-to-market and time-to-volume of new and established products.

To achieve consistent success with our customers, we must balance several key attributes such as time-to-market, time-to-volume, quality, cost, service, price and a broad product portfolio. Our operating results will be adversely affected if we fail to:

• maintain overall quality of products in new and established programs;

• produce sufficient quantities of products at the capacities our customers demand while managing the integration of new and established technologies;

• develop and qualify new products that have changes in overall specifications or features that our customers may require for their business needs;

• obtain commitments from our customers to qualify new products, redesigns of current products, or new components in our existing products;

• obtain customer qualification of these products on a timely basis by meeting all of our customers’ needs for performance, quality and features;

• maintain an adequate supply of components required to manufacture our products; or

• maintain the manufacturing capability to quickly change our product mix between different capacities, form factors and spin speeds in response to changes in customers’ product demands.

40

Manufacturing outside the United States and marketing our products globally subjects us to numerous risks.

We are subject to risks associated with our global manufacturing operations and global marketing efforts, including:

• obtaining requisite U.S. and foreign governmental permits and approvals;

• currency exchange rate fluctuations or restrictions;

• political instability and civil unrest;

• limited transportation availability, delays, and extended time required for shipping, which risks may be compounded in periods of price declines;

• higher freight rates;

• labor problems;

• trade restrictions or higher tariffs;

• copyright levies or similar fees or taxes imposed in European and other countries;

• exchange, currency and tax controls and reallocations;

• increasing labor and overhead costs; and

• loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities.

Terrorist attacks may adversely affect our business and operating results.

The continued threat of terrorist activity and other acts of war or hostility have created uncertainty in the financial and insurance markets and have significantly increased the political, economic and social instability in some of the geographic areas in which we operate. Additionally, it is uncertain what impact the reactions to such acts by various governmental agencies and security regulators worldwide will have on shipping costs. Acts of terrorism, either domestically or abroad, could create further uncertainties and instability. To the extent this results in disruption or delays of our manufacturing capabilities or shipments of our products, our business, operating results and financial condition could be adversely affected.

Sudden disruptions to the availability of freight lanes could have an impact on our operations.

We generally ship our products to our customers, and receive shipments from our suppliers, via air, ocean or land freight. The sudden unavailability or disruption of cargo operations or freight lanes, such as due to labor difficulties or disputes, severe weather patterns or other natural disasters, or political instability or civil unrest, could impact our operating results by impairing our ability to timely and efficiently deliver our products.

41

We are vulnerable to system failures or attacks, which could harm our business.

We are heavily dependent on our technology infrastructure, among other functions, to operate our factories, sell our products, fulfill orders, manage inventory and bill, collect and make payments. Our systems are vulnerable to damage or interruption from natural disasters, power loss, telecommunication failures, computer viruses, computer denial-of-service attacks and other events. Our business is also subject to break-ins, sabotage and intentional acts of vandalism by third parties as well as employees. Despite any precautions we may take, such problems could result in, among other consequences, interruptions in our business, which could harm our reputation and financial condition.

If we fail to identify, manage, complete and integrate acquisitions, investment opportunities or other significant transactions, it may adversely affect our future results.

As part of our growth strategy, we may pursue acquisitions of, investment opportunities in or other significant transactions with companies that are complementary to our business. In order to pursue this strategy successfully, we must identify attractive acquisition or investment opportunities, successfully complete the transaction, some of which may be large and complex, and manage post-closing issues such as integration of the acquired company or employees. We may not be able to identify or complete appealing acquisition or investment opportunities given the intense competition for these transactions. Even if we identify and complete suitable corporate transactions, we may not be able to successfully address any integration challenges in a timely manner, or at all. If we fail to successfully integrate an acquisition, we may not realize all or any of the anticipated benefits of the acquisition, and our future results of operations could be adversely affected.

If we are unable to retain or hire key staff and skilled employees our business results may suffer.

Our success depends upon the continued contributions of our key staff and skilled employees, many of whom would be extremely difficult to replace. Global competition for skilled employees in the data storage industry is intense and, as we attempt to move to a position of technology leadership in the storage industry, our business success becomes increasingly dependent on our ability to retain our key staff and skilled employees as well as attract, integrate and retain new skilled employees. Volatility or lack of positive performance in our stock price and the overall markets may adversely affect our ability to retain key staff or skilled employees who have received equity compensation. Additionally, because a substantial portion of our key employees’ compensation is placed “at risk” and linked to the performance of our business, when our operating results are negatively impacted by global economic conditions, we are at a competitive disadvantage for retaining and hiring key staff and skilled employees versus other companies that pay a relatively higher fixed salary. If we are unable to retain our existing key staff or skilled employees, or hire and integrate new key staff or skilled employees, or if we fail to implement succession plans for our key staff, our operating results would likely be harmed.

The nature of our business and our reliance on intellectual property and other proprietary information subjects us to the risk of significant litigation.

The data storage industry has been characterized by significant litigation. This includes litigation relating to patent and other intellectual property rights, product liability claims and other types of litigation. Litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of litigation are inherently uncertain and may result in adverse rulings or decisions. We may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on our business, financial condition or operating results.

We evaluate notices of alleged patent infringement and notices of patents from patent holders that we receive from time to time. If claims or actions are asserted against us, we may be required to obtain a license or cross-license, modify our existing technology or design a new non-infringing technology. Such licenses or design modifications can be extremely costly. In addition, we may decide to settle a claim or action against us, which settlement could be costly. We may also be liable for any past infringement. If there is an adverse ruling against us in an infringement lawsuit, an injunction could be issued barring production or sale of any infringing product. It could also result in a damage award equal to a reasonable royalty or lost profits or, if there is a finding of willful infringement, treble damages. Any of these results would increase our costs and harm our operating results.

42

Our reliance on intellectual property and other proprietary information subjects us to the risk that these key ingredients of our business could be copied by competitors.

Our success depends, in significant part, on the proprietary nature of our technology, including non-patentable intellectual property such as our process technology. If a competitor is able to reproduce or otherwise capitalize on our technology despite the safeguards we have in place, it may be difficult, expensive or impossible for us to obtain necessary legal protection. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do U.S. laws. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We rely upon employee, consultant and vendor non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. However, any of our registered or unregistered intellectual property rights may be challenged or exploited by others in the industry, which might harm our operating results.

The costs of compliance with state, federal and international legal and regulatory requirements, such as environmental, labor, trade and tax regulations, and customers’ standards of corporate citizenship could cause an increase in our operating costs.

We may be or become subject to various state, federal and international laws and regulations governing our environmental, labor, trade and tax practices. These laws and regulations, particularly those applicable to our international operations, are or may be complex, extensive and subject to change. We will need to ensure that we and our component suppliers timely comply with such laws and regulations, which may result in an increase in our operating costs. For example, the European Union (“EU”) has enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) directive, which prohibits the use of certain substances in electronic equipment, and the Waste Electrical and Electronic Equipment (“WEEE”) directive, which obligates parties that place electrical and electronic equipment onto the market in the EU to put a clearly identifiable mark on the equipment, register with and report to EU member countries regarding distribution of the equipment, and provide a mechanism to take back and properly dispose of the equipment. Similar legislation may be enacted in other locations where we manufacture or sell our products. In addition, climate change and financial reform legislation in the United States is a significant topic of discussion and has generated and may continue to generate federal or other regulatory responses in the near future. If we or our component suppliers fail to timely comply with applicable legislation, our customers may refuse to purchase our products or we may face increased operating costs as a result of taxes, fines or penalties, which would have a materially adverse effect on our business, financial condition and operating results.

In connection with our compliance with such environmental laws and regulations, as well as our compliance with industry environmental initiatives, the standards of business conduct required by some of our customers, and our commitment to sound corporate citizenship in all aspects of our business, we could incur substantial compliance and operating costs and be subject to disruptions to our operations and logistics. In addition, if we were found to be in violation of these laws or noncompliant with these initiatives or standards of conduct, we could be subject to governmental fines, liability to our customers and damage to our reputation and corporate brand which could cause our financial condition or operating results to suffer.

Fluctuations in currency exchange rates as a result of our international operations may negatively affect our operating results.

Because we manufacture and sell our products abroad, our revenue, margins, operating costs and cash flows are impacted by fluctuations in foreign currency exchange rates. If the U.S. dollar exhibits sustained weakness against most foreign currencies, the U.S. dollar equivalents of unhedged manufacturing costs could increase because a significant portion of our production costs are foreign-currency denominated. Conversely, there would not be an offsetting impact to revenues since revenues are substantially U.S. dollar denominated. Additionally, we negotiate and procure some of our component requirements in U.S. dollars from Japanese and other non-U.S. based vendors. If the U.S. dollar continues to weaken against other foreign currencies, some of our component suppliers may increase the price they charge for their components in order to maintain an equivalent profit margin. If this occurs, it would have a negative impact on our operating results.

43

Prices for our products are substantially U.S. dollar denominated, even when sold to customers that are located outside the United States. Therefore, as a substantial portion of our sales are from countries outside the United States, fluctuations in currency exchanges rates, most notably the strengthening of the U.S. dollar against other foreign currencies, contribute to variations in sales of products in impacted jurisdictions and could adversely impact demand and revenue growth. In addition, currency variations can adversely affect margins on sales of our products in countries outside the United States.

We have attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term, foreign exchange contracts. However, these contracts do not cover our full exposure and can be canceled by the counterparty if currency controls are put in place. Currently, we hedge the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling with foreign exchange contracts.

Increases in our customers’ credit risk could result in credit losses and an increase in our operating costs.

Some of our OEM customers have adopted a subcontractor model that requires us to contract directly with companies, such as ODMs, that provide manufacturing and fulfillment services to our OEM customers. Because these subcontractors are generally not as well capitalized as our direct OEM customers, this subcontractor model exposes us to increased credit risks. Our agreements with our OEM customers may not permit us to increase our product prices to alleviate this increased credit risk. Additionally, as we attempt to expand our OEM and distribution channel sales into emerging economies such as Brazil, Russia, India and China, the customers with the most success in these regions may have relatively short operating histories, making it more difficult for us to accurately assess the associated credit risks. Any credit losses we may suffer as a result of these increased risks, or as a result of credit losses from any significant customer, would increase our operating costs, which may negatively impact our operating results.

Inaccurate projections of demand for our product can cause large fluctuations in our quarterly results.

We often ship a high percentage of our total quarterly sales in the third month of the quarter, which makes it difficult for us to forecast our financial results before the end of the quarter. In addition, our quarterly projections and results may be subject to significant fluctuations as a result of a number of other factors including:

• the timing of orders from and shipment of products to major customers;

• our product mix;

• changes in the prices of our products;

• manufacturing delays or interruptions;

• acceptance by customers of competing products in lieu of our products;

• variations in the cost of and lead times for components for our products;

• limited availability of components that we obtain from a single or a limited number of suppliers;

• competition and consolidation in the data storage industry;

• seasonal and other fluctuations in demand for PCs often due to technological advances; and

• availability and rates of transportation.

Rapidly changing conditions in the hard drive industry make it difficult to predict actual results.

We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting. The highly technical nature of our products and the rapidly changing market conditions with which we deal means that actual results may differ significantly from our estimates and assumptions. These changes have impacted our financial results in the past and may continue to do so in the future. Key estimates and assumptions for us include:

• price protection adjustments and other sales promotions and allowances on products sold to retailers, resellers and distributors;

• inventory adjustments for write-down of inventories to lower of cost or market value (net realizable value);

• reserves for doubtful accounts;

44

• accruals for product returns;

• accruals for warranty costs related to product defects;

• accruals for litigation and other contingencies;

• liabilities for unrecognized tax benefits; and

• expensing of stock-based compensation.

The market price of our common stock is volatile.

The market price of our common stock has been, and may continue to be, extremely volatile. Factors such as the following may significantly affect the market price of our common stock:

• actual or anticipated fluctuations in our operating results, including those resulting from the seasonality of our business;

• announcements of technological innovations by us or our competitors which may decrease the volume and profitability of sales of our existing products and increase the risk of inventory obsolescence;

• new products introduced by us or our competitors;

• periods of severe pricing pressures due to oversupply or price erosion resulting from competitive pressures or industry consolidation;

• developments with respect to patents or proprietary rights;

• conditions and trends in the hard drive, computer, data and content management, storage and communication industries;

• contraction in our operating results or growth rates that are lower than our previous high growth-rate periods;

• changes in financial estimates by securities analysts relating specifically to us or the hard drive industry in general;

• macroeconomic conditions that affect the market generally; and

• uncertainties regarding our planned acquisition of HGST.

In addition, general economic conditions may cause the stock market to experience extreme price and volume fluctuations from time to time that particularly affect the stock prices of many high technology companies. These fluctuations often appear to be unrelated to the operating performance of the companies.

Securities class action lawsuits are often brought against companies after periods of volatility in the market price of their securities. A number of such suits have been filed against us in the past, and should any new lawsuits be filed, such matters could result in substantial costs and a diversion of resources and management’s attention.

Current economic conditions have caused us difficulty in adequately protecting our increased cash and cash equivalents from financial institution failures.

The uncertain global economic conditions and volatile investment markets have caused us to hold more cash and cash equivalents than we would hold under normal circumstances. Since there has been an overall increase in demand for low-risk, U.S. government-backed securities with a limited supply in the financial marketplace, we face increased difficulty in adequately protecting our increased cash and cash equivalents from possible sudden and unforeseeable failures by banks and other financial institutions. A failure of any of these financial institutions in which deposits exceed FDIC limits could have an adverse impact on our financial position.

45

If our internal controls are found to be ineffective, our financial results or our stock price may be adversely affected.

Our most recent evaluation resulted in our conclusion that as of July 2, 2010, in compliance with Section 404 of the Sarbanes-Oxley Act of 2002, our internal control over financial reporting was effective. We believe that we currently have adequate internal control procedures in place for future periods; however, if our internal control over financial reporting is found to be ineffective or if we identify a material weakness or significant deficiency in our financial reporting, investors may lose confidence in the reliability of our financial statements, which may adversely affect our financial results or our stock price.

From time to time we may become subject to income tax audits or similar proceedings, and as a result we may incur additional costs and expenses or owe additional taxes, interest and penalties that may negatively impact our operating results.

We are subject to income taxes in the United States and certain foreign jurisdictions, and our determination of our tax liability is subject to review by applicable domestic and foreign tax authorities. For example, as we have previously disclosed, we are under examination by the IRS for certain fiscal years and in connection with that examination, we received Revenue Agent Reports seeking certain adjustments to income as disclosed in Part I, Item 1, Note 6 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q. Although we believe our tax positions are properly supported, the final timing and resolution of the notice of proposed adjustment and the audits are subject to significant uncertainty and could result in our having to pay amounts to the applicable tax authority in order to resolve examination of our tax positions, which could result in an increase or decrease of our current estimate of unrecognized tax benefits and may negatively impact our financial position, results of operations, net income or cash flows.
