INDEPENDENT AUDITORS' REPORT Retirement Plan Committee of the Board of Directors Western Digital Corporation Retirement Savings and Profit Sharing Plan: We have audited the accompanying statements of net assets available for plan benefits of the Western Digital Corporation Retirement Savings and Profit Sharing Plan (the "Plan") as of June 30, 2000 and 2001 and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Western Digital Corporation Retirement Savings and Profit Sharing Plan as of June 30, 2000 and 2001, and the changes in net assets available for plan benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets (Held at End of Year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

WESTERN DIGITAL CORPORATION RETIREMENT SAVINGS AND PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS JUNE 30, 2000 AND 2001 (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements of the Western Digital Corporation Retirement Savings and Profit Sharing Plan (the "Plan"), formerly known as the Western Digital Corporation Savings and Profit Sharing Plan, have been prepared on an accrual basis of accounting and present the net assets available for Plan benefits as of June 30, 2000 and 2001 and changes in net assets available for Plan benefits for the years ended June 30, 2000 and 2001. Valuation of Investments Investments in marketable securities and common stock traded on national securities exchanges are valued at current market values, determined through reference to public market information on the last business day of the Plan's fiscal year. Securities not traded on the last business day are valued at the last reported bid price. At June 30, 2000 and 2001, the Plan held investments in mutual funds, which are reported at fair market value. Purchases and sales of securities are recorded on a trade-date basis. Participant loans are carried at their outstanding balance which approximates fair market value. Income Tax Status The Internal Revenue Service has determined and informed Western Digital Corporation (the "Company") by a letter dated January 17, 1997, that the Plan is designed in accordance with applicable sections of the Internal Revenue Code ("IRC"). The Plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the requirements of the IRC. Use of Estimates The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates. (2) DESCRIPTION OF THE PLAN General The Plan is a defined contribution plan as defined by the Employee Retirement Income Security Act of 1974. Participants should refer to the Plan document for a more complete description of the Plan's provisions. Contributions U.S.-based employees of the Company, who meet the Plan's eligibility criteria, are eligible to participate in the Plan and to receive employer matching contributions. Eligible employees may elect to contribute up to 14% of their compensation on a pretax basis and 9% of their compensation on an after tax basis (with an aggregate limit of 14%) for investment in 11 funds, provided that contributions do not exceed IRS limitations. The Company may make contributions equal to 50% of pretax participant contributions to the 8

WESTERN DIGITAL CORPORATION RETIREMENT SAVINGS AND PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) Plan, up to the first 5% of the participant's compensation. Effective January 1, 2000 the Plan was amended to limit the Company's aggregate maximum matching contribution to $2,000 for any calendar year. The Company may also make additional contributions at its discretion. The Company may suspend matching contributions when it does not have sufficient net profits to make the applicable matching contribution. Contributions to the Plan are recorded as soon as administratively possible after the Company makes payroll deductions from Plan participants.

WESTERN DIGITAL CORPORATION RETIREMENT SAVINGS AND PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) Participant Loans Loans can be made to a participant up to an amount equal to the lesser of $50,000 reduced by the participant's highest outstanding balance during the preceding 12 months or 50% of a participant's vested account balance. The loans bear interest at 1% above the current prime rate published by T. Rowe Price Trust Company and are generally payable in installments over periods ranging from one to five years, unless the loan is used for the purchase of a primary residence, in which case the repayment period may be up to ten years. Principal and interest payments are allocated to the participants' accounts in the same manner as their current contributions. The Plan allows participants to have no more than two active loans at a time. The annual interest rate charged on employee loans during 2001 ranged from 7.0% to 10.5%. Participant Accounts A separate account is maintained for each participant in each designated fund. Each account is adjusted for contributions and net investment income or loss on a daily basis. Net investment income or loss is allocated to the accounts in the same proportion as the participant's beginning account balance invested in the fund (as defined in the Plan) bears to the total of all participants' beginning account balances invested in the fund. Payment of Benefits Upon termination, participants may receive a lump-sum payment in cash and/or shares of the Company's common stock. The nonvested portion of terminated participants' accounts is forfeited subject to a five-year reinstatement period. Forfeitures are allocated annually to remaining participants in the same ratio as each participant's compensation for the plan year bears to the total compensation for the plan year of all participants eligible to share in the allocation. Certain restrictions apply to withdrawals of amounts from the Plan while a participant continues to be employed by the Company. Vesting Participants are at all times one hundred percent vested in the value of their voluntary contributions and the Company's profit sharing contributions. A participant is fully vested in the Company's matching contributions and earnings thereon after five years of service (as defined in the Plan), or upon retirement (at normal retirement age), permanent disability or death. The Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan, subject to the provisions of the Employee Retirement Income Security Act of 1974. In the event of Plan termination, participants will become fully vested in their accounts. Administration of the Plan The Retirement Plan Committee (the "Committee"), appointed by the Board of Directors and consisting of at least three members, has the authority to control and manage the operation and administration of the Plan. The assets of the Plan are held in a non-discretionary trust by T. Rowe Price Trust Company as trustee and are administered under a trust agreement which requires that the trustee hold, administer and distribute the funds of the Plan in accordance with the text of the Plan and the instructions of the Committee or its designees. The compensation or fees of accountants, counsel and other specialists and any other costs of administering the Plan or the trust are paid by the Company or charged to the trust at the discretion of the Company. 11

WESTERN DIGITAL CORPORATION RETIREMENT SAVINGS AND PROFIT SHARING PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) (3) PROFIT SHARING FEATURE The Company adopted an annual profit sharing feature effective as of the beginning of the Company's 1992 fiscal year. All eligible domestic employees of the Company who are employed on the last day of the Company's fiscal year are eligible to participate in the profit sharing component. The amount of profit sharing paid to participants is dependent upon their eligible compensation earned during the fiscal year. A portion of each eligible participant's allocation of the Company's profit sharing contribution is deposited into an individual profit sharing account established under the Plan (0% of eligible fiscal year compensation in 2000 and 2001, respectively) and the excess allocable to such participant, if any, is paid as a fiscal year-end cash bonus. Benefits are generally payable following retirement, disability, death, hardship or termination of employment. During 2000 and 2001, the Company did not authorize any defined pre-tax profits to be allocated to the participants and contributed $0 as profit sharing to the Plan.
