Dear Michael:

This letter, when signed by you, constitutes the agreement (the "Agreement")
relative to your retirement from Western Digital Corporation ("WDC") and Western
Digital Technologies, Inc. ("WDT" and, collectively with WDC, the "Company"). In
consideration for the covenants and releases contained herein, you and the
Company agree as follows:

1.     TRANSITION PERIOD. You voluntarily retired from your position as Vice
       President, Law and Administration, and Secretary of WDC and WDT, and from
       all of your other positions with the Company's other subsidiaries,
       effective Thursday, March 28, 2002. Effective such date, you will
       continue to be an employee of WDC, subject to the limitations below, and

       the earlier of March 31, 2003, earlier termination by the Company as
       provided in this Section 1, or your death (the "Transition Period").
       During the Transition Period, you will report to the Company's Chairman
       and Chief Executive Officer and will coordinate with the Vice President,
       General Counsel and Secretary, and shall perform such transitional duties
       as assigned from time to time, including, but not limited to, managing
       the Company's Intellectual Property Department (IPD) within the Legal
       department until the Company reassigns these responsibilities to another
       individual. You will also be responsible for project specific assignments
       as directed from time to time. It is intended that (i) from March 28,
       2002 through June 30, 2002, you will work as a full-time employee with a
       forty (40) hour work week; (ii) from July 1, 2002, through September 30,
       2002, you will work as a part-time employee with a thirty (30) hour work
       week; (iii) from October 1, 2002, through December 31, 2002, you will
       work as a part-time employee with a twenty (20) hour work week; and (iv)

       part-time employee with a ten (10) hour work week. If you terminate the
       Transition Period and your employment with the Company before March 31,
       2003, you are required to give at least two weeks' written notice. In
       such an event, your Transition Period, and any entitlement to
       compensation or vesting under this Agreement, shall cease on the
       fourteenth day following



                                                        Mr. Michael A. Cornelius
                                                                  March 31, 2002
                                                                          Page 2




       the date on which notice is given. The Company retains the right to
       terminate the Transition Period at any time. Should this occur, the
       Transition Period end-date will be determined at the time of such an
       event.

2.     STOCK OPTIONS AND RESTRICTED SHARES.

       (a)    During the Transition Period, any stock options previously granted
              to you under the Company's Employee Stock Option Plan and the
              Company's subsidiary's Stock Incentive Plans (collectively, the
              "Options") will continue to vest in accordance with their terms.
              At the end of Transition Period, all of your Options will become
              fully vested, and you will have up to three (3) years following
              the later of March 31, 2003 or the end of the Transition Period to
              exercise any or all such Options or, in the event of your death,
              such longer period as may be provided in the Options. A stock
              option summary and detailed schedule setting forth these Options,
              their grant dates, exercise prices, and vesting schedules is being
              delivered to you separately and is incorporated herein by
              reference.


       (b)    Upon your full performance through the Transition Period all
              remaining unvested restricted stock (the "Restricted Shares")
              awarded you in December 2000 will vest. Should the Company
              terminate the Transition Period any time prior to March 31, 2003,
              all unvested restricted stock awarded you in December 2000 will
              vest.


       (c)    Notwithstanding anything to the contrary in this Agreement, if you
              breach any of your covenants set forth in paragraphs 9, 10, 11, or
              13 hereof, (i) any unexercised Options shall be deemed immediately
              canceled and shall no longer be exercisable, (ii) the Restricted
              Shares shall be deemed immediately canceled, and (iii) WDC and/or
              WDT shall have the right to recover any profits realized by you as
              a result of the exercise of Options or the sale of Restricted
              Shares or of shares received pursuant to the exercise of Options
              during the six month period prior to the date of any such breach,
              as determined by the Board of Directors.


3.     COMPENSATION.

       (a)    During the Transition Period, you will be paid at the following
              base salary wage rate: (i) $22,917 per month through June 30,
              2002; (ii) $17,188 per month from June 1, 2002, through September
              30, 2002; (iii) $11,459 per month from October 1, 2002, through

              through March 31, 2003. Should the Company terminate the
              Transition Period any time prior to March 31, 2003, you will be
              given a one-time lump sum payment as determined by calculating the
              time remaining from the new Transition Period end-date to March
              31, 2003, per the above base salary wage rate schedule.

       (b)    During the Transition Period, you will be a participant in the
              Company's Change of Control (COC) Severance Plan ("Severance
              Plan") and are eligible to participate at


                                                        Mr. Michael A. Cornelius
                                                                  March 31, 2002
                                                                          Page 3




              the Executive Officer 16(b) level at the Company, even though you
              will not be a 16(b) Executive Officer. You will participate on a
              prorated basis as defined by your then current part-time
              employment status.

4.     BENEFITS. Your eligibility and level of participation for benefits during
       the Transition Period will be determined by your full-time or part-time
       employee status and pay grade. You will receive the full $5,000.00
       Financial Planning benefit regardless of your employment status
       throughout the Transition Period.

       Upon completion or termination of the Transition Period, March 31, 2003,
       or earlier, you will be given a one-time lump sum payment equal to 18
       months of your then current monthly medical insurance premiums, including
       Executive Medical benefits, as then paid by the Company. This payment
       will be grossed up to cover the net cost and will not take into account
       any estimated escalation in future cost increases.

5.     CONFIDENTIALITY AND COMMUNICATIONS. You and the Company agree that the
       terms of this Agreement will be held in confidence except to the extent
       that disclosures may be required by government regulations or judicial
       process or to receive tax, legal or financial advice. References that may
       request information about your employment will be referred to the Vice
       President of Human Resources.

6.     VACATION. You will continue to accrue vacation hours during the
       Transition Period per Company Policy as determined by your full-time or
       part-time employee status and number of years at the Company.

7.     INCENTIVE COMPENSATION PLAN (ICP). You will be eligible to participate in
       the Company's Incentive Compensation Plan (ICP) during the Transition
       Period. The potential ICP percentage payout is sixty-five percent (65%)
       of base salary and will be prorated as determined by your full-time or
       part-time employee status. Should the Company terminate the Transition
       Period any time prior to March 31, 2003, you will be given a one-time
       lump sum payment as if you had been employed through March 31, 2003,
       taking into account your part-time employment status per the base salary
       wage rate schedule under "Section 3. Compensation" of this agreement, and
       considering any proration consequences of the then current ICP period.
       Further, the prorated payment will be equivalent to one hundred percent
       (100%) of the ICP funding for your position for the then current ICP
       period. Calculation for the payment will be made at the end of the then
       current ICP period and paid at such time as all then current employees.

8.     INDEMNIFICATION AND ASSISTANCE.

       (a)    If you are subjected to any claim or demand involving any action
              or inaction allegedly taken by you during the course of your
              employment or directorship with the Company, you will be entitled
              to all rights of indemnification that may then be available to
              other executive officers or directors of the Company, including,
              without limitation, insurance protection under any director and/or
              officer liability insurance coverage maintained by the Company or

                                                                          Page 4

              have or may have with respect to actual and/or potential disputes
              arising out of the activities of the Company during the period you
              were employed by the Company. You further agree to submit to
              deposition and/or testimony in accordance with the laws of the
              forum involved concerning any knowledge you have or may have with

       work, advice, consulting, or other services to a competitor of the
       Company, whether as an employee, independent contractor, adviser,
       volunteer, director or in any other capacity, for any individual,
       partnership, corporation, or other business entity, without using,
       disclosing, evaluating or relying upon the Company's proprietary and
       confidential information. Accordingly, you agree that during the
       Transition Period and for a period of one (1) year thereafter you will
       not directly or indirectly, whether for your own account or as an
       employee, director, consultant or advisor, provide services to any
       business or engage in any business which at the time of commencement of
       such services is, or is expected to be, competitive with the Company's or
       any of its subsidiaries' product lines or business activities, unless you
       obtain the prior written consent of the Company's Chief Executive
       Officer.

10.    NON-SOLICITATION OF EMPLOYEES. You agree that during the Transition
       Period and for a period of one (1) year thereafter you will not directly

       its subsidiaries') employ for any reason or interfere in any other manner
       with the employment relationships at the time existing between the
       Company (or any if its subsidiaries) and its current or prospective
       employees.

       licensor, licensee or other business relation of the Company (or any of
       its subsidiaries) to cease doing business with the Company (or any of its
       subsidiaries) or in any way interfere with the existing business
       relationship between any such customer, supplier, distributor, licensor,
       licensee or other business relation and the Company (or any of its
       subsidiaries).

12.    IRREPARABLE HARM. You agree that the Company would be irreparably harmed
       by any breach or threatened breach of the agreements in Paragraphs 9, 10
       and 11 and that, therefore, the Company shall be entitled to an
       injunction prohibiting you from any breach or threatened breach of such
       agreements.

13.    NON-DISPARAGEMENT. You and the Company agree that each shall not (1)
       directly or indirectly, make or ratify any statement, public or private,
       oral or written, to any person that disparages, either professionally or
       personally, the other party, the other party's subsidiaries and
       affiliates, past and present, and each of them, as well as its and their
       trustees, directors, officers, agents, employees, stockholders,
       representatives, assigns, and successors, past and present, and each of
       them, or (2) make any statement or engage in any conduct that has the
       purpose or effect of disrupting the business of the other party,
       provided, however, that each party shall respond accurately and fully to
       any question, inquiry or request for information when required by legal
       process.

14.    CONFIDENTIAL INFORMATION. When you joined the Company you signed an
       agreement setting forth your obligations to the Company during and after
       your employment. A copy of your agreement is being delivered to you
       separately and is incorporated herein by reference. You understand and
       agree that in the course of your employment with the Company, you have
       acquired confidential information and trade secrets concerning the
       Company's business and financial operating plans and budgets, its
       strategic business plans and those of its subsidiaries, and its
       personnel. You understand and agree it could be extremely damaging to the
       Company if you disclosed such information to a competitor or made it
       available to any other person or company. You understand and agree that
       such information has been divulged to you in confidence, and you
       understand and agree that you will keep such information secret and
       confidential unless disclosure is required by court order or otherwise by
       compulsion of law. In view of the nature of your employment and the
       information and trade secrets which you have had access to during the
       course of your employment, you also agree that the Company would be
       irreparably harmed by any breach, or threatened breach of the agreements
       in this Paragraph and that, therefore, the Company shall be entitled to
       an injunction prohibiting you from any breach or threatened breach of
       such agreements.

15.    RELEASE OF CLAIMS. You agree that pursuant to this Agreement, the Company
       is providing consideration beyond the obligations owed to you by the
       Company or any subsidiary of the Company prior to entering this
       Agreement. You, on behalf of yourself and your heirs, agents,
       representatives, immediate family members, executors, successors, and

       shall not be effective until the revocation period has expired. You
       acknowledge that under ADEA you have at least twenty-one (21) days under
       which to consider this agreement. After due consideration and
       consultation with your attorney, you have hereby knowingly and
       voluntarily waived this requirement. Any revocation should be in writing
       and delivered in accordance with the notice provisions of Paragraph 23
       hereof by close of business on the seventh day from the date that you

17.    CIVIL CODE SECTION 1542. You represent that you are not aware of any
       claim other than the claims that are released by this Agreement. You
       acknowledge that you have been advised by legal counsel and are familiar
       with the provisions of California Civil Code Section 1542, which provides
       as follows:

           A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
           NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
           THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
           SETTLEMENT WITH THE DEBTOR.

       You, being aware of said code section, agree to expressly waive any
       rights you may have thereunder, as well as under any other federal or
       state statute or common law principles of similar effect.

18.    REMEDIES IN EVENT OF FUTURE DISPUTE.

       (a)    Except as provided in subparagraph (b) below, in the event of any
              future dispute, controversy or claim between you and the Company,
              whether arising from or relating to this Agreement, its breach,
              any matter addressed by this Agreement, your employment with the
              Company before and through the Transition Period, or otherwise,
              you and the Company will first attempt to resolve the dispute
              through confidential non-binding mediation to be conducted in
              Orange County, California by


                                                        Mr. Michael A. Cornelius
                                                                  March 31, 2002
                                                                          Page 8




              JAMS-Endispute or such other mediator as you and the Company shall
              mutually agree upon. If the dispute is not resolved through
              mediation, you and the Company will submit it to final and binding
              confidential arbitration to be conducted in Orange County,
              California by JAMS/Endispute in accordance with the then existing
              JAMS/Endispute Arbitration Rules and Procedures for Employment
              Disputes. In the event of such an arbitration proceeding, you and
              the Company shall select a mutually acceptable neutral arbitrator
              from among the JAMS/Endispute panel of arbitrators. If you and the
              Company cannot agree on an arbitrator, the Administrator of
              JAMS/Endispute shall appoint an arbitrator. None of you, the
              Company or the arbitrator shall disclose the existence, content,
              or results of any arbitration hereunder without the prior written
              consent of both of you and the Company, except as may be compelled
              by court order. Except as provided herein, the Federal Arbitration
              Act shall govern the interpretation and enforcement of such
              arbitration and all proceedings. The arbitrator shall apply the
              substantive law (and the law of remedies, if applicable) of the
              State of California, or Federal law, or both, as applicable, and
              the arbitrator is without jurisdiction to apply any different
              substantive law. The arbitrator shall render an award and a
              written, reasoned opinion in support thereof. Judgment upon the
              award may be entered in any court having jurisdiction thereof. You
              and the Company intend this arbitration provision to be valid,
              enforceable, irrevocable and construed as broadly as possible.

       (b)    In the event that a dispute arises concerning compliance with this
              Agreement, either you or the Company will be entitled to obtain
              from a court with jurisdiction over you and the Company
              preliminary and permanent injunctive relief to enjoin or restrict
              the other party from such breach or to enjoin or restrict a third
              party from inducing any such breach, and other appropriate relief,
              including money damages. By seeking any such relief, however, the
              moving party shall not be relieved of such party's obligation
              hereunder to have any remaining portion of the controversy
              resolved by binding confidential arbitration in accordance with
              subparagraph (a) above.

       (c)    The Company shall pay the forum costs for any such arbitration.
              The prevailing party in any such arbitration or court proceeding
              shall be entitled to recover from the losing party such of his or
              its reasonable costs and expenses, including reasonable attorneys'
              fees, incurred in connection with the arbitration or court
              proceeding as would be recoverable had such party's claim been
              brought as a civil action in a court of competent jurisdiction.

19.    ASSIGNMENT. The rights and obligations of the Company under this
       Agreement shall inure to the benefit of and shall be binding upon the
       present and future subsidiaries of the Company, any and all subsidiaries
       of a subsidiary, all affiliated corporations, and successors and assigns
       of the Company. No assignment of this Agreement by the Company will
       relieve the Company of its obligations. You shall not assign any of your
       rights and/or obligations under this Agreement and any such attempted
       assignment will be void. This Agreement shall be binding upon and inure
       to the benefit of your heirs, executors, administrators, or other legal
       representatives and their legal assigns.

20.    WAIVER. A waiver by either you or the Company of any of the terms or
