For Immediate Release

MATT MASSENGILL APPOINTED PRESIDENT, CEO OF WESTERN DIGITAL AND ELECTED TO
BOARD; TOM PARDUN APPOINTED CHAIRMAN OF THE BOARD; CHUCK HAGGERTY RETIRING

IRVINE, CA. - January 13, 2000- The Board of Directors of Western Digital
Corporation (NYSE:WDC) has appointed Matthew E. Massengill president and chief
executive officer and elected him to the board, effective immediately.
Massengill, 38, has been with the California-based manufacturer of storage
solutions for 14 years, and most recently has been serving as chief operating
officer. Thomas E. Pardun, president of MediaOne International-Asia/Pacific and
a Western Digital director since 1993, was elected chairman of the board of
directors. Pardun, 56, will become chairman of the Western Digital board upon
completion of the merger between AT&T Corp. and MediaOne Group Inc. Chuck
Haggerty, 58, has resigned as president and chief executive officer and will
retire as chairman.

During 1999, Massengill led efforts to stabilize the Company's core hard drive
business through improved new product performance and manufacturing efficiencies
and has been leading Western Digital's repositioning as a data/content
storage-management company in both PC and non-PC markets. In 1999, the Company
returned to time-to- market leadership in its core desktop hard drive business
and removed $150 million in annualized costs from its manufacturing operations.
WD also recently launched new businesses in networked attached storage through
its Connex subsidiary, in home entertainment storage with its WD Performer
drives, and in data warehousing through its SageTree subsidiary.

Pardun, who will retire from MediaOne when it completes its merger with ATT, has
a 35-year career in the media, telecommunications and computer industries. Prior
to his current position, Pardun was president and chief executive officer of US
WEST Multimedia Communications (MediaOne became a separate company from US WEST
in 1998). During his 12 years at US WEST/MediaOne, Pardun held senior management
positions including vice president and general manager of business and
government services and vice president of marketing and planning for US WEST
Communications. Earlier in his career, Pardun was a division and group president
of Sprint Communications and began his career with IBM where he spent 19 years
in various marketing and product management assignments.

Western Digital's search for a new chief executive began in mid-1999 when
Haggerty announced his plan to retire before the end of the current fiscal year.
He has served Western Digital for more than seven years and has been in the high
technology industry for 36 years.

Pardun said, "Our search committee found no one in the company or in the larger
business community with talents, experience, enthusiasm and knowledge to equal
those of Matt Massengill. Matt has great energy, operating experience and a
clear vision of the future for Western Digital. He is clearly the right leader
for this company as we move into the 21st century."

"Western Digital has core technology, intellectual property and brand equity
that are enabling us to expand our market reach and re-invent the company," said
Massengill. "In our traditional hard drive markets, where the landscape has
changed dramatically, we have taken steps to establish WD as the low-cost
provider of hard drives. Leveraging our core strengths, we are entering new
storage-related markets with higher value propositions designed to greatly
enhance the WD business model."

"I am delighted to be leading this great company at such an exciting juncture
and working in partnership with Tom Pardun to realize its potential," said
Massengill. "I have known and worked with Tom throughout his six years as a
Western Digital director and look forward to his counsel as chairman."

Massengill joined Western Digital in 1985 as a product engineer. He held various
engineering and marketing positions in the company's desktop hard drive business
from the late 1980's to the mid 1990's when Western Digital grew from a small
HDD supplier to become one of the largest global supplier of hard drives in the
desktop personal computer market.

He led the Enterprise Storage Group in 1997 as senior vice president and general
manager, returning to the company's headquarters to lead the Drive Products
Division when the company's desktop and enterprise-class hard drive operations
were combined in 1998. Massengill was appointed executive vice president,
worldwide operations and geographies in early 1999 and was subsequently named
co-chief operating officer in August 1999. He was named chief operating officer
in October.

Before joining Western Digital, Massengill served Ford Aerospace and
Communications Corporation for three years as a research engineer developing
materials and devices for infrared detectors and imaging systems. He received
his degree in engineering from Purdue University in 1983, and in 1988 was
honored by Purdue with its Outstanding Engineering Alumni award.

Western Digital Corporation is a leading manufacturer of hard drives used for
information storage in desktop computers, servers, workstations and home
