NAMED EXECUTIVE OFFICERS

     Base Salaries. The current annual base salaries for the current executive officers of Western Digital Corporation (the “Company”) who were named in the Summary Compensation Table in the Company’s Proxy Statement that was filed with the Securities and Exchange Commission in connection with the Company’s 2007 Annual Meeting of Stockholders (the “Named Executive Officers”) are as follows:

Named Executive Officer		Title		Current Base Salary
John F. Coyne		President and Chief Executive Officer		$	800,000
Timothy M. Leyden		Executive Vice President and Chief Financial Officer		$	450,000
Raymond M. Bukaty		Senior Vice President, Administration, General Counsel and Secretary		$	400,000
Hossein Moghadam		Senior Vice President, Chief Technology Officer		$	400,000

     Semi-Annual Bonuses. Under the Company’s Incentive Compensation Plan (the “ICP”), the Named Executive Officers are also eligible to receive semi-annual cash bonus awards that are determined based on the Company’s achievement of performance goals pre-established by the Compensation Committee (the “Committee”) of the Company’s Board of Directors as well as other discretionary factors. On November 5, 2007, the Committee established the performance goals for the cash bonus awards payable for the six-month period beginning December 31, 2007 and ending June 27, 2008. Specifically, the Committee selected earnings per share as the financial performance goal and established specific earnings per share goals to correspond to specific achievement percentages ranging between 0% and 200%.

     At the end of the six-month performance period, the ICP will fund in an amount ranging from 0% to 200% based on an interpolation between the Company’s performance as measured against the pre-established earnings per share goals and other discretionary considerations. Each Named Executive Officer will be eligible to receive a bonus in an amount equal to his target bonus percentage multiplied by the funding percentage approved by the Committee, subject to further adjustment in the discretion of the Committee depending upon the executive’s individual and business group performance. The target bonus percentages for the Named Executive Officers under the ICP currently range from 75% to 125% of each Named Executive Officer’s semi-annual base salary.

     Additional Compensation. The Named Executive Officers are also eligible to receive equity-based incentives and discretionary bonuses as determined from time to time by the Committee, are entitled to participate in various Company plans, and are subject to other written agreements, in each case as set forth in exhibits to the Company’s filings with the Securities and Exchange Commission. In addition, the Named Executive Officers may be eligible to receive perquisites and other personal benefits as disclosed in the Company’s Proxy Statement that was filed with the Securities and Exchange Commission in connection with the Company’s 2007 Annual Meeting of Stockholders.
