Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions that address the evolving needs of the information technology (“IT”) industry and the infrastructure that enables the proliferation of data in virtually every other industry. The Company creates environments for data to thrive. The Company is driving the innovation needed to help customers capture, preserve, access and transform an ever-increasing diversity of data. Everywhere data lives, from advanced data centers to mobile sensors to personal devices, the Company’s industry-leading solutions deliver the possibilities of data. The Company’s broad portfolio of technology and products address the following key end markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. The Company also generates license and royalty revenue from its extensive intellectual property (“IP”), which is included in each of these three end market categories. The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the fiscal year ended July 3, 2020. In the opinion of management, all adjustments necessary to fairly state the 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 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 fiscal year ended July 3, 2020. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Fiscal Year The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2021, which ends on July 2, 2021, will be comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Fiscal year 2020, which ended on July 3, 2020, was comprised of 53 weeks, with the first quarter consisting of 14 weeks and the remaining quarters consisting of 13 weeks each. Use of Estimates 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 with consideration given to the potential impacts of the coronavirus disease 2019 (“COVID-19”) pandemic. However, actual results could differ materially from these estimates and be significantly affected by the severity and duration of the pandemic, the extent of actions to contain or treat COVID-19, including the effects of ongoing vaccination efforts, how quickly and to what extent normal economic and operating activity can resume, and the severity and duration of the global economic downturn that results from the pandemic. Segment Information The Company manufactures, markets, and sells data storage devices and solutions in the U.S. and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. Historically, the Company has managed and reported under a single operating segment. Late in the first quarter of fiscal 2021, the Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), announced a decision to reorganize the Company’s business by forming two separate product business units: flash-based products and hard disk drives (“HDD”). The Company is in the process of transitioning to this new operating model and discrete information has not yet been established to align with the new business structure. Management expects to finalize its assessment of its operating segments when the transition is completed, which is expected to be by the end of fiscal 2021.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments are effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2019, which for the Company is the first quarter of fiscal 2021. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements. In November 2018, the FASB issued ASU No. 2018-18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606” (“ASU 2018-18”). ASU 2018-18 clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. This ASU requires retrospective adoption to the date the Company adopted Accounting Standards Codification (ASC) 606 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. This ASU is effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2020, which for the Company is the first quarter of fiscal 2022. Early adoption is permitted. The Company does not expect this update to have a material impact on its Condensed Consolidated Financial Statements.

Revenues

Revenue from Contract with Customer [Abstract]
Revenues	Revenues Contract assets represent the Company’s rights to consideration where performance obligations are completed but the customer payments are not due until another performance obligation is satisfied. The Company did not have any contract assets as of either January 1, 2021 or July 3, 2020. The Company incurs sales commissions and other direct incremental costs to obtain sales contracts. The Company has applied the practical expedient to recognize the direct incremental costs of obtaining contracts as an expense when incurred if the amortization period is expected to be one year or less or the amount is not material, with these costs charged to Selling, general and administrative expenses. Other direct incremental costs to obtain contracts that have an expected benefit of greater than one year are amortized over the period of expected cash flows from the related contracts, and the amortization expense is recorded as a reduction to revenue. Total capitalized contract costs as of January 1, 2021 and July 3, 2020 as well as the related amortization for the three and six months ended January 1, 2021 and January 3, 2020 were not material. Contract liabilities relate to customers’ payments in advance of performance under the contract and primarily relate to remaining performance obligations under support and maintenance contracts. As of January 1, 2021 and July 3, 2020, contract liabilities were not material. The Company applies the practical expedients and does not disclose transaction price allocated to the remaining performance obligations for (i) arrangements that have an original expected duration of one year or less, which mainly consist of support and maintenance contracts, and (ii) variable consideration amounts for sale-based or usage-based royalties for IP license arrangements, which typically range longer than one year. Remaining performance obligations are mainly attributed to right-to-access patent license arrangements and customer support and service contracts, which will be recognized over the remaining contract period. The transaction price allocated to the remaining performance obligations as of January 1, 2021 was $91 million, which is mainly attributable to the functional IP license and service arrangements. The Company expects to recognize this amount as revenue as follows: $20 million during the remainder of fiscal 2021, $40 million in fiscal 2022, and $31 million in fiscal 2023 and thereafter. The Company’s disaggregated revenue information is as follows: Three Months Ended Six Months Ended January 1, January 3, January 1, January 3, (in millions) Revenue by Product HDD $ 1,909 $ 2,396 $ 3,753 $ 4,804 Flash-based 2,034 1,838 4,112 3,470 Total Revenue $ 3,943 $ 4,234 $ 7,865 $ 8,274 Revenue by End Market Client Devices $ 2,131 $ 1,797 $ 4,077 $ 3,413 Data Center Devices & Solutions 807 1,489 1,936 3,021 Client Solutions 1,005 948 1,852 1,840 Total Revenue $ 3,943 $ 4,234 $ 7,865 $ 8,274 Revenue by Geography Americas $ 945 $ 1,296 $ 2,024 $ 2,609 Europe, Middle East and Africa 725 811 1,354 1,590 Asia 2,273 2,127 4,487 4,075 Total Revenue $ 3,943 $ 4,234 $ 7,865 $ 8,274 The Company’s top 10 customers accounted for 43% and 41% of its net revenue for the three and six months ended January 1, 2021, respectively, and 44% and 43% of its net revenue for the three and six months ended January 3, 2020, respectively. For the three and six months ended January 1, 2021 and January 3, 2020, no single customer accounted for 10% or more of the Company’s net revenue.

Supplemental Financial Statement Data	Supplemental Financial Statement Data Accounts receivable, net From time to time, in connection with factoring agreements, the Company sells trade accounts receivable without recourse to third party purchasers in exchange for cash. During the six months ended January 1, 2021 and January 3, 2020, the Company sold trade accounts receivable and received cash proceeds of $173 million and $198 million, respectively. The discounts on the trade accounts receivable sold during the periods were not material and were recorded within Other income, net in the Condensed Consolidated Statements of Operations. As of January 1, 2021 and July 3, 2020, the amount of factored receivables that remained outstanding was $45 million and $113 million, respectively.

IPR&D is initially accounted for as an indefinite-lived intangible asset. Once a project reaches technological feasibility, the Company reclassifies the balance to existing technology and begins to amortize the intangible asset over its estimated useful life.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Investments	Fair Value Measurements and Investments Financial Instruments Carried at Fair Value 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. 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 tables present information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of January 1, 2021 and July 3, 2020, and indicate the fair value hierarchy of the valuation techniques utilized to determine such values: January 1, 2021 Level 1 Level 2 Level 3 Total (in millions) Assets: Cash equivalents - Money market funds $ 806 $ — $ — $ 806 Foreign exchange contracts — 33 — 33 Total assets at fair value $ 806 $ 33 $ — $ 839 Liabilities: Foreign exchange contracts $ — $ 16 $ — $ 16 Interest rate swap contract — 109 — 109 Total liabilities at fair value $ — $ 125 $ — $ 125 July 3, 2020 Level 1 Level 2 Level 3 Total (in millions) Assets: Cash equivalents - Money market funds $ 1,079 $ — $ — $ 1,079 Foreign exchange contracts — 28 — 28 Total assets at fair value $ 1,079 $ 28 $ — $ 1,107 Liabilities: Foreign exchange contracts $ — $ 9 $ — $ 9 Interest rate swap contract — 133 — 133 Total liabilities at fair value $ — $ 142 $ — $ 142 During the three and six months ended January 1, 2021 and January 3, 2020, the Company had no transfers of financial assets and liabilities between levels and there were no changes in valuation techniques or the inputs used in the fair value measurement. Financial Instruments Not Carried at Fair Value The carrying value of the Company’s revolving credit facility approximates its fair value given the revolving nature of the balance and the variable market interest rate. For financial instruments where the carrying value (which includes principal adjusted for any unamortized issuance costs, and discounts or premiums) differs from fair value (which is based on quoted market prices), the following table represents the related carrying value and fair value for each of the Company’s outstanding financial instruments. Each of the financial instruments presented below was categorized as Level 2 for all periods presented, based on the frequency of trading immediately prior to the end of the second quarter of 2021 and the fourth quarter of 2020, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities As of January 1, 2021, the Company had outstanding foreign exchange forward contracts that were designated as either cash flow hedges or non-designated hedges. Substantially all of the contract maturity dates of these foreign exchange forward contracts do not exceed 12 months. In addition, the Company had outstanding pay-fixed interest rate swaps that were designated as cash flow hedges of variable rate interest payments on a portion of its term loans through February 2023. As of January 1, 2021, the amount of existing net losses related to cash flow hedges recorded in AOCI included $57 million related to the Company’s interest rate swaps that is expected to be reclassified to earnings after twelve months. In addition, as of January 1, 2021, the Company did not have any foreign exchange forward contracts with credit-risk-related contingent features. Changes in fair values of the non-designated foreign exchange contracts are recognized in Other income, net and are largely offset by corresponding changes in the fair values of the foreign currency denominated monetary assets and liabilities. For each of the three and six months ended January 1, 2021 and January 3, 2020, total net realized and unrealized transaction and foreign exchange contract currency gains and losses were not material to the Company’s Condensed Consolidated Financial Statements. Netting Arrangements Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of offset associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. As of January 1, 2021 and July 3, 2020, the effect of rights of offset was not material and the Company did not offset or net the fair value amounts of derivative instruments in its Condensed Consolidated Balance Sheets.

Related Parties and Related Commitments and Contingencies	Related Parties and Related Commitments and Contingencies Flash Ventures The Company’s business ventures with Kioxia Corporation (“Kioxia”) consist of three separate legal entities: Flash Partners Ltd. (“Flash Partners”), Flash Alliance Ltd. (“Flash Alliance”), and Flash Forward Ltd. (“Flash Forward”), collectively referred to as “Flash Ventures”. The following table presents the notes receivable from, and equity investments in, Flash Ventures as of January 1, 2021 and July 3, 2020: January 1, July 3, (in millions) Notes receivable, Flash Partners $ 330 $ 273 Notes receivable, Flash Alliance 197 301 Notes receivable, Flash Forward 666 670 Investment in Flash Partners 214 203 Investment in Flash Alliance 315 300 Investment in Flash Forward 136 128 Total notes receivable and investments in Flash Ventures $ 1,858 $ 1,875 During the three and six months ended January 1, 2021 and during the three and six months ended January 3, 2020, the Company made net payments to Flash Ventures of $1.21 billion and $2.19 billion, and $648 million and $1.33 billion, respectively, for purchased flash-based memory wafers and net loans and investments. The Company makes, or will make, loans to Flash Ventures to fund equipment investments for new process technologies and additional wafer capacity. The Company aggregates its Flash Ventures’ notes receivable into one class of financing receivables due to the similar ownership interest and common structure in each Flash Venture entity. For all reporting periods presented, no loans were past due and no loan impairments were recorded. The Company’s notes receivable from each Flash Ventures entity, denominated in Japanese yen, are secured by equipment owned by that Flash Ventures entity. As of January 1, 2021 and July 3, 2020, the Company had Accounts payable balances due to Flash Ventures of $393 million and $407 million, respectively. The Company’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Ventures, based upon the Japanese yen to U.S. dollar exchange rate at January 1, 2021, is presented below. Investments in Flash Ventures are denominated in Japanese yen, and the maximum estimable loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar. January 1, (in millions) Notes receivable $ 1,193 Equity investments 665 Operating lease guarantees 2,107 Inventory and prepayments 662 Maximum estimable loss exposure $ 4,627 The Company is obligated to pay for variable costs incurred in producing its share of Flash Ventures’ flash-based memory wafer supply, based on its three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, the Company is obligated to pay for half of Flash Ventures’ fixed costs regardless of the output the Company chooses to purchase. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50.0% of each Flash Ventures entity’s capital investments to the extent that each Flash Ventures entity’s operating cash flow is insufficient to fund these investments. In June 2019, an unexpected power outage incident occurred at the flash-based memory manufacturing facilities operated in Yokkaichi, Japan. The power outage incident impacted the facilities and process tools and resulted in damage to flash wafers in production and a reduction in the Company’s flash wafer availability. As a result of this incident, the Company incurred charges of $68 million for the six months ended January 3, 2020, which were recorded in Cost of revenue and primarily consisted of unabsorbed manufacturing overhead costs. During the six months ended January 1, 2021, the Company recovered $75 million related to this incident from its insurance carriers, which was recorded in Cost of revenue. In May 2019, the Company entered into additional agreements with Kioxia to extend Flash Ventures to a new wafer fabrication facility, known as “K1,” located in Kitakami, Japan. The primary purpose of K1 is to provide clean room space to continue the transition of existing flash-based wafer capacity to newer technology nodes. K1 is now fully operational. In connection with the start-up of this facility, the Company agreed to prepay an aggregate of approximately $360 million over a 3-year period beginning in the first half of fiscal year 2020 toward K1 building depreciation, to be credited against future wafer charges. As of January 1, 2021, remaining committed prepayments totaled $149 million. Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled. Research and Development Activities. The Company participates in common research and development (“R&D”) activities with Kioxia and is contractually committed to a minimum funding level. R&D commitments are immaterial to the Condensed Consolidated Financial Statements. Off-Balance Sheet Liabilities Flash Ventures sells to and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which the Company guarantees half or all of the outstanding obligations under each lease agreement. The lease agreements are subject to customary covenants and cancellation events related to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of Flash Ventures’ obligations and a call on the Company’s guarantees. The following table presents the Company’s portion of the remaining guarantee obligations under the Flash Ventures’ lease facilities in both Japanese yen and U.S. dollar-equivalent, based upon the Japanese yen to U.S. dollar exchange rate as of January 1, 2021. Lease Amounts (Japanese yen, in billions) (U.S. dollar, in millions) Total guarantee obligations ¥ 217 $ 2,107 The following table details the breakdown of the Company’s remaining guarantee obligations between the principal amortization and the purchase option exercise price at the end of the term of the Flash Ventures lease agreements, in annual installments as of January 1, 2021 in U.S. dollars, based upon the Japanese yen to U.S. dollar exchange rate as of January 1, 2021: Annual Installments Payment of Principal Amortization Purchase Option Exercise Price at Final Lease Terms Guarantee Amount (in millions) Remaining six months of 2021 $ 294 $ 63 $ 357 2022 524 52 576 2023 409 70 479 2024 238 126 364 2025 77 116 193 Thereafter 28 110 138 Total guarantee obligations $ 1,570 $ 537 $ 2,107 The Company and Kioxia have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. The Company has not made any indemnification payments, nor recorded any indemnification receivables, under any such agreements. As of January 1, 2021, no amounts have been accrued in the Condensed Consolidated Financial Statements with respect to these indemnification agreements. Unis Venture

Income Tax Expense

Income Tax Expense	6 Months Ended

Income Tax Disclosure [Abstract]
Income Tax Expense	Income Tax Expense On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic in the U.S. The CARES Act, among other things, allows net operating losses arising in tax years 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes and increases the business interest expense limitation from 30% to 50% of adjusted taxable income for tax years 2019 and 2020. Additionally, countries around the world continue to implement emergency tax measures to provide relief similar to the CARES Act. The Company at present does not expect that any of the provisions of the CARES Act or the emergency tax measures around the world would result in a material cash benefit. On December 27, 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was enacted to fund the federal government through their fiscal year, extend certain expiring tax provisions and provide additional emergency relief to individuals and businesses related to the COVID-19 pandemic in the U.S. The Company at present does not expect any of the provisions of the Appropriations Act to have a material impact on its financial statements. The Company continues to monitor and evaluate the regulatory and interpretive guidance related to the CARES Act and the Appropriations Act, as well as legislation in other jurisdictions. The Tax Cuts and Jobs Act (the “2017 Act”), enacted on December 22, 2017, includes a broad range of tax reform proposals affecting businesses. The Company completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of fiscal 2019. However, the U.S. Treasury and the Internal Revenue Service (“IRS”) have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and the Company anticipates the issuance of additional regulatory and interpretive guidance. The Company applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to the Company’s estimates in future periods. The following table presents the Company’s Income tax expense and the effective tax rate: Three Months Ended Six Months Ended January 1, January 3, January 1, January 3, ($ in millions) Income (loss) before taxes $ 85 $ (40) $ 82 $ (277) Income tax expense 23 99 80 138 Effective tax rate 27 % (248) % 98 % (50) % The primary drivers of the difference between the effective tax rate for the three and six months ended January 1, 2021 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand that will expire at various dates during fiscal years 2021 through 2030. In addition, the effective tax rate for the three and six months ended January 1, 2021 includes the discrete effects of favorable adjustments proposed by tax authorities of $8 million. The effective tax rate for the six months ended January 1, 2021 also includes the discrete effects of net tax deficiencies from shortfalls of $12 million related to the vesting of stock-based awards and additional tax expense of $10 million from the re-measurement of deferred tax liabilities due to restructuring activities, which have no impact on the amount of income taxes paid by the Company. The primary drivers of the difference between the effective tax rate for the three and six months ended January 3, 2020 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, Philippines and Thailand that expired or will expire at various dates during fiscal years 2020 through 2030. The IRS previously completed its field examination of the Company’s federal income tax returns for fiscal years 2008 through 2012 and proposed certain adjustments. As previously disclosed, the Company received Revenue Agent Reports from the IRS for fiscal years 2008 through 2009, proposing adjustments relating to transfer pricing with the Company’s foreign subsidiaries and intercompany payable balances. The Company disagrees with the proposed adjustments and in September 2015, filed a protest with the IRS Appeals Office and received the IRS rebuttal in July 2016. The Company and the IRS Appeals Office did not reach a settlement on the disputed matters. On June 28, 2018, the IRS issued a statutory notice of deficiency with respect to the disputed matters for fiscal years 2008 through 2009, seeking to increase the Company’s U.S. taxable income by an amount that would result in additional federal tax through fiscal year 2009 totaling approximately $516 million, subject to interest and penalties. The Company filed a petition with the U.S. Tax Court in September 2018. On December 10, 2018, the IRS issued a statutory notice of deficiency with respect to fiscal years 2010 through 2012, seeking to increase the Company’s U.S. taxable income by an amount that would result in additional federal tax for fiscal years 2010 through 2012 totaling approximately $549 million, subject to interest and penalties. Approximately $535 million of the total additional federal tax for fiscal years 2010 through 2012 relates to proposed adjustments for transfer pricing with the Company’s foreign subsidiaries, intercompany payable balances and the utilization of certain tax attributes. The Company filed a petition with the U.S. Tax Court in March 2019. The U.S. Tax Court consolidated the case for fiscal years 2008 through 2009 with the case for fiscal years 2010 through 2012. On May 4, 2020, the IRS filed with the U.S. Tax Court Amendments to Answer to assert penalties totaling $340 million on the proposed adjustments relating to transfer pricing with respect to fiscal years 2008 through 2009 and fiscal years 2010 through 2012. In September 2020 and December 2020, the IRS proposed adjustments relating to transfer pricing with the Company’s foreign subsidiaries and intercompany payable balances for fiscal years 2013 through 2015 that, if sustained, would result in additional federal tax totaling approximately $343 million. The Company disagrees with the proposed adjustments and continues to believe that its tax positions are properly supported and will vigorously contest the position taken by the IRS. The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations 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 January 1, 2021, it was not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns. As of January 1, 2021, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $715 million. Accrued interest and penalties related to unrecognized tax benefits as of January 1, 2021 was approximately $146 million. Of these amounts, approximately $724 million could result in potential cash payments. The Company is not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.

Diluted income (loss) per common share is computed using Net income (loss) and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include dilutive outstanding employee stock options, RSUs and PSUs, and rights to purchase shares of common stock under the Company’s ESPP. For the three and six months ended January 3, 2020, the Company recorded net loss, and all shares subject to outstanding equity awards have been excluded for those periods because including them would be anti-dilutive.

Legal Proceedings	Legal Proceedings Tax For disclosures regarding statutory notices of deficiency issued by the IRS on June 28, 2018 and December 10, 2018, and petitions filed by the Company with the U.S. Tax Court in September 2018 and March 2019, see Note 12, Income Tax Expense. Other Matters In the normal course of business, the Company is subject to 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, management believes that any monetary liability or financial impact to the Company from these matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, any monetary liability and financial impact to the Company from these matters could differ materially from the Company’s expectations.

Organization and Basis of Presentation (Policies)	6 Months Ended
	Jan. 01, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions that address the evolving needs of the information technology (“IT”) industry and the infrastructure that enables the proliferation of data in virtually every other industry. The Company creates environments for data to thrive. The Company is driving the innovation needed to help customers capture, preserve, access and transform an ever-increasing diversity of data. Everywhere data lives, from advanced data centers to mobile sensors to personal devices, the Company’s industry-leading solutions deliver the possibilities of data. The Company’s broad portfolio of technology and products address the following key end markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. The Company also generates license and royalty revenue from its extensive intellectual property (“IP”), which is included in each of these three end market categories. The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the fiscal year ended July 3, 2020. In the opinion of management, all adjustments necessary to fairly state the 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 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 fiscal year ended July 3, 2020. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.
Fiscal Year	Fiscal YearThe Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2021, which ends on July 2, 2021, will be comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Fiscal year 2020, which ended on July 3, 2020, was comprised of 53 weeks, with the first quarter consisting of 14 weeks and the remaining quarters consisting of 13 weeks each.
Use of Estimates	Use of Estimates 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 with consideration given to the potential impacts of the coronavirus disease 2019 (“COVID-19”) pandemic. However, actual results could differ materially from these estimates and be significantly affected by the severity and duration of the pandemic, the extent of actions to contain or treat COVID-19, including the effects of ongoing vaccination efforts, how quickly and to what extent normal economic and operating activity can resume, and the severity and duration of the global economic downturn that results from the pandemic.
Segment Information	Segment Information The Company manufactures, markets, and sells data storage devices and solutions in the U.S. and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. Historically, the Company has managed and reported under a single operating segment. Late in the first quarter of fiscal 2021, the Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), announced a decision to reorganize the Company’s business by forming two separate product business units: flash-based products and hard disk drives (“HDD”). The Company is in the process of transitioning to this new operating model and discrete information has not yet been established to align with the new business structure. Management expects to finalize its assessment of its operating segments when the transition is completed, which is expected to be by the end of fiscal 2021.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments are effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2019, which for the Company is the first quarter of fiscal 2021. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements. In November 2018, the FASB issued ASU No. 2018-18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606” (“ASU 2018-18”). ASU 2018-18 clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. This ASU requires retrospective adoption to the date the Company adopted Accounting Standards Codification (ASC) 606 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. This ASU is effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2020, which for the Company is the first quarter of fiscal 2022. Early adoption is permitted. The Company does not expect this update to have a material impact on its Condensed Consolidated Financial Statements.
Fair Value Measurements and Investments	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. 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.
