WESTERN DIGITAL ANNOUNCES Q2 REVENUE, UNITS, EPS WILL EXCEED GUIDANCE;
$14 MILLION OPERATING PROFIT EXPECTED FROM HDD BUSINESS


TO INCREASE COST EFFICIENCIES AND MAINTAIN MANUFACTURING FLEXIBILITY, COMPANY
SIGNS AGREEMENT TO ACQUIRE THAILAND FACILITY FROM FUJITSU

LAKE FOREST, Calif. -- Dec. 20, 2001 -- Western Digital Corp. (NYSE: WDC) today
announced that revenue, unit shipments and profitability for its second fiscal
quarter ending December 28, 2001 are expected to exceed its earlier guidance.

The Company expects Q2 revenue in the range of $540 million to $550 million on
unit shipments of approximately 7.5 million. Earnings per share are expected to
be approximately $.04 -- the Company's first profit on a consolidated basis
excluding non-recurring items since the quarter ending December 1998. Western
Digital had earlier said it would post revenue in the range of $490 million to
$520 million on unit shipments of 6 million to 6.5 million, and would break even
or report a profit of $.01 per share for the quarter. In the year-ago period,
the Company reported revenue of $562 million on unit shipments of 6.1 million
and a loss of $.04 per share, excluding non-recurring items.

The anticipated Q2 results include an operating profit of approximately $14
million from the hard drive business, compared with an operating profit of $12
million in the second quarter of fiscal 2001 and $4 million in the first quarter
of fiscal 2002.(1)

The Company will announce its final results for the second fiscal quarter after
the market closes on January 24, 2002.

"Better-than-expected demand for WD hard drives from all our channels in the PC
industry underscored the strengths of our product portfolio, customer base, and
business model," said Matt Massengill, chairman, chief executive officer and
president of Western Digital. "We had anticipated solid sequential growth this
quarter based on increases in drive shipments to Microsoft for its Xbox gaming
system and from additional volumes caused by Fujitsu's exit from the desktop HDD
business. In addition to these factors, the upside came from the strength of
demand in the PC sector and our ability to meet that demand with our broadened
family of products."

Separately, Western Digital announced it has signed a definitive agreement with
Fujitsu (Thailand) Company Ltd. to purchase a 155,000-square foot hard drive and
head stack assembly facility near Bangkok, Thailand. The transaction, which is
expected to close in January, will include land, building and equipment. The
purchase price was not disclosed and will not be material to Western Digital's
current or future capital expenditures.

"The addition of this facility and its highly-trained HDD and head-stacking
workforce will ensure that our manufacturing model remains highly-focused and
cost efficient, and continues to have the flexibility to quickly shift mix in
response to customer needs," said Arif Shakeel, executive vice president and
chief operating officer of Western Digital. "As we bring on this new capability,
we will maintain Western Digital's operating philosophy

                                       4

of managing build plans to meet existing market demand. At the same time, this
step will help mitigate the potential risks of having all HDD manufacturing
conducted in a single site."

Shakeel indicated that the Thailand facility will complement WD's existing
manufacturing facility in Kuala Lumpur, Malaysia, by providing both head stack
assembly and final assembly of its value line of hard drives. The Thailand
facility will be retrofitted to the Company's processes and quality standards
and is expected to be operational during the March quarter.

1. The prior year results reflect the previously announced restatements for the
adoption of SEC Staff Accounting Bulletin No. 101 and reclassification of the
Company's Connex and SANavigator businesses as discontinued operations.
