                          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, 1998 and 1999 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,
1998 and 1999, 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.

                          NOTES TO FINANCIAL STATEMENTS
                             JUNE 30, 1998 AND 1999

(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, 1998 and 1999 and changes in net
    assets available for Plan benefits for the years ended June 30, 1998 and
    1999.

    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, 1998 and 1999, 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 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 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, up to the first 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

    after the Company makes payroll deductions from Plan participants.

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 1999 ranged from 7.0% to 11.9%.

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 (0% of eligible
fiscal year compensation in 1998 and 1999) 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 1998 and 1999, the Company did not authorize
any defined pre-tax profits to be allocated to the participants. In 1998 and
1999, the Company did not contribute to the profit sharing feature of the Plan.
