                          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, 1997 and 1998 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 generally accepted auditing
standards. 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,
1997 and 1998, and the changes in net assets available for plan benefits for the
years then ended in conformity with generally accepted accounting principles.

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
for Investment Purposes, Schedule of Loans or Fixed Income Obligations and 
Schedule of Reportable Transactions are presented for the purpose of additional
analysis and are not a required part of the basic financial statements but are
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 schedules have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are 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


(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, 1997 and 1998 and
        changes in net assets available for Plan benefits for the years ended
        June 30, 1997 and 1998.

        Valuation of Investments
        ------------------------

        Investments in marketable securities and common stock traded on national
        security 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, 1997 and
        1998, the Plan held investments in mutual funds, which are reported at
        fair market value. Cash and cash equivalents are valued at cost plus
        accrued interest which approximates market. Participant loans are
        carried at their contract value 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 generally
        accepted accounting principles 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 12 funds, provided that contributions do not
        exceed IRS limitations. The Company may make contributions equal to 50%
        of pretax participant contributions to the Plan, which are limited to 5%
        of the participant's compensation. The Company may also make additional
        contributions at its discretion. The Company may suspend matching
        contributions when it does not have

        On June 30, 1997, the Plan closed the Disciplined Equity Fund and
        transferred all participant balances invested in this fund into any or
        all of the remaining funds offered by the Plan as instructed by the
        individual participants. In the event that no designation was made by a
        participant, amounts invested in the Disciplined Equity Fund were
        transferred to the Stable Value Fund at June 30, 1997.

        As of June 30, 1998, all of the Plan's assets were invested in mutual
        funds, Western Digital common stock, cash and cash equivalents or
        participant loans. Participants may transfer all or a portion of the
        balance in their accounts between investment funds on a daily basis.

        Participant Loans
        -----------------

        Loans can be made to a participant up to an amount equal to the lesser
        of $50,000 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 1998 ranged from 7% to 10%.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


        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.

        (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 (6.0% and 0% of
        eligible fiscal year compensation in 1997 and 1998, 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 1997 and 1998, the Company authorized 4.1% and 0%, respectively,
        of defined pre-tax profits to be allocated to the participants. In 1997
        and 1998, the Company contributed $7,141,684 and $0, respectively, as
        profit sharing to the Plan.
