has relentlessly focused on quality and reliability in its products, efficiency
in its manufacturing operations and asset management, and excellence in its
customer and supply chain relationships. Today, the company is the world's
second largest manufacturer of hard drives. Under this management team, WD has
more than doubled its revenue from $2.0 billion in fiscal 2000 to $4.3 billion
in fiscal 2006, grown its profitability from a loss of $188 million to income of
$396 million, expanded its cash and short-term investments from $184 million to
$699 million, and posted one of the industry's leading returns on invested
capital.

     Coyne is a veteran of the international electronics business and has
dedicated the majority of his career to WD. In the last several years, his
responsibilities gradually have expanded beyond worldwide manufacturing
operations to include all business operations, materials, sales, and customer
satisfaction. He was named president and chief operating officer earlier this
year; he served as executive vice president and chief operations officer
beginning in 2005, and as senior vice president, worldwide operations from 2000
to 2005. Beginning in 2003, Coyne led the integration of the acquired assets of

native Ireland. Coyne holds a bachelor's degree in mechanical engineering from
