NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

To Be Held On November 14, 2013

To the Stockholders of
WESTERN DIGITAL CORPORATION:

Our 2013 Annual Meeting of Stockholders will be held at 3333 Michelson Drive, Irvine, California 92612 on Thursday,

November 14, 2013 at 8:00 a.m., local time, for the following purposes:

1. To elect the twelve director nominees named in the attached Proxy Statement to serve until our next annual

meeting of stockholders and until their successors are duly elected and qualified;

2. To approve on an advisory basis the named executive officer compensation disclosed in this Proxy Statement;
3. To ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year

ending June 27, 2014; and

4. To transact such other business as may properly come before the Annual Meeting or any postponement or

adjournment of the meeting.
Any action on the items described above may be considered at the Annual Meeting at the time and on the date specified

above or at any time and date to which the Annual Meeting is properly adjourned or postponed.

Only stockholders of record at the close of business on September 17, 2013 are entitled to notice of and to vote at the

Annual Meeting and any adjournments or postponements of the meeting.

We are using the Securities and Exchange Commission rule that allows companies to furnish their proxy materials over

the Internet. As a result, we are mailing to most of our stockholders a "Notice of Internet Availability of Proxy Materials," or
Notice, instead of a printed copy of the Proxy Statement and our Annual Report for the fiscal year ended June 28, 2013. The
Notice contains instructions on how stockholders can access those documents over the Internet and vote their shares. The
Notice also contains instructions on how each of those stockholders can receive a printed copy of our proxy materials,
including the Proxy Statement, our 2013 Annual Report and a proxy card or voting instruction form. All stockholders who do
not receive a Notice will receive a printed copy of the proxy materials by mail. We believe this process will expedite
stockholders' receipt of proxy materials, lower the costs of our Annual Meeting and conserve natural resources.

By Order of the Board of Directors
