REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Shareholders
Western Digital Corporation:
We have audited the accompanying consolidated balance sheets of Western Digital Corporation and subsidiaries
as of June 28, 2013 and June 29, 2012, and the related consolidated statements of income, comprehensive income,
shareholders' equity, and cash flows for each of the years in the three-year period ended June 28, 2013. In connection
with our audits of the consolidated financial statements, we have also audited the related financial statement schedule.
These consolidated financial statements and financial statement schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated financial statements and financial
statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). 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, evi-
dence 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 consolidated financial statements referred to above present fairly, in all material respects, the
financial position of Western Digital Corporation and subsidiaries as of June 28, 2013 and June 29, 2012, and the
results of their operations and their cash flows for each of the years in the three-year period ended June 28, 2013, in
conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement
schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly,
in all material respects, the information set forth therein.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Western Digital Corporation's internal control over financial reporting as of June 28, 2013, based on
criteria established in Internal Control -- Integrated Framework issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO), and our report dated August 16, 2013, expressed an unqualified opinion on the
effectiveness of the Company's internal control over financial reporting.
