Item 1.01         Entry into a Material Definitive Agreement.

                  On August 25, 2005, Western Digital Corporation ("Western
Digital") entered into (i) an Employment Agreement with Arif Shakeel (the
"Shakeel Employment Agreement"), pursuant to which Mr. Shakeel will become Chief
Executive Officer of Western Digital, effective October 1, 2005, and (ii) an
Employment Agreement with Matthew E. Massengill (the "Massengill Employment
Agreement"), pursuant to which Mr. Massengill will relinquish the role of Chief
Executive Officer of Western Digital, effective October 1, 2005, and will
continue to serve as Chairman of the Board of Directors.

                  Pursuant to the Shakeel Employment Agreement, a copy of which
is attached hereto as Exhibit 10.1 and incorporated herein by reference, Mr.
Shakeel will continue to serve as President and Chief Operating Officer until
September 30, 2005. Effective October 1, 2005, Mr. Shakeel will become Chief
Executive Officer and President. The Shakeel Employment Agreement runs through
January 1, 2008, subject to certain termination provisions.

                  The Shakeel Employment Agreement provides for Mr. Shakeel to
receive base salary at the annual rate of $700,000 until October 1, 2005, at
which time the annual rate of Mr. Shakeel's base salary will increase to
$800,000. Mr. Shakeel's target annual bonus will be 100% of his base salary, and
he will be entitled to participate in Western Digital's other benefit plans on
terms consistent with those generally applicable to Western Digital's other
senior executives.

                  Pursuant to the agreement, Mr. Shakeel has been granted an
award of 1,250,000 restricted shares of Western Digital's common stock. Subject
to Mr. Shakeel's continued employment by Western Digital, 500,000 of these
restricted shares will vest on January 1, 2007, and the remaining 750,000 of
these restricted shares will vest on January 1, 2008. Mr. Shakeel's outstanding
stock options and restricted shares, to the extent that such options and such
restricted shares were scheduled to vest after December 31, 2007, have been
cancelled pursuant to the agreement. Also pursuant to the agreement, the entire
performance share award granted to Mr. Shakeel on or about January 20, 2005, has
been cancelled.

                  If Western Digital terminates Mr. Shakeel's employment other
than for cause (as defined in the agreement) prior to January 1, 2008, Mr.
Shakeel will be entitled to (i) a lump sum cash payment equal to his base salary
and target bonus for the period between the date his employment terminates and
January 1, 2008, and (ii) accelerated vesting of any and all options and other
equity-based awards granted by Western Digital that are then outstanding and not
otherwise fully vested, but only to the extent such awards were otherwise
scheduled to vest before January 1, 2008.

                  Pursuant to the Massengill Employment Agreement, a copy of
which is attached hereto as Exhibit 10.2 and incorporated herein by reference,
Mr. Massengill will continue to serve as Chairman of the Board and Chief
Executive Officer until September 30, 2005. Effective October 1, 2005, Mr.
Massengill will relinquish the role of Chief Executive Officer and will continue
employment as Chairman of the Board or in such other executive capacity as may
be assigned by the Board. Mr. Massengill's duties as Chairman of the Board will
include offering assistance to Mr. Shakeel in his new position as Chief
Executive Officer and coordinating investor communications. The Massengill
Employment Agreement runs through January 1, 2007, subject to certain
termination provisions.

                  The Massengill Employment Agreement provides for Mr.
Massengill to continue to receive base salary at his current annual rate of
$800,000. Mr. Massengill's target annual bonus will be 100% of his base salary,
and he will be entitled to participate in Western Digital's other benefit plans
on terms consistent with those generally applicable to Western Digital's other
senior executives.

                  Mr. Massengill's outstanding stock options and restricted
shares, to the extent that such options and such restricted shares were
scheduled to vest after July 31, 2007, have been cancelled pursuant to the
agreement. Provided that Mr. Massengill remains employed by Western Digital
through January 1, 2007, any of his outstanding stock options and any of his
restricted shares that are scheduled to vest after January 1, 2007 and on or
before July 31, 2007 will accelerate and become vested on January 1, 2007. With
respect to the accelerated options, Mr. Massengill will have until the later of
(i) January 1, 2010, or (ii) the time the options would have otherwise expired
or been terminated in accordance with the termination of employment rules
otherwise applicable to the options (but in no event later than the expiration
date of the options) to exercise those options. Also pursuant to the agreement,
the entire performance share award granted to Mr. Massengill on or about January
20, 2005, has been cancelled.

salary and target bonus for the period between the date his employment
terminates and January 1, 2007, and (ii) accelerated vesting of any and all
