Exhibit 10.3

SEPARATION AND GENERAL RELEASE AGREEMENT

This Separation and General Release Agreement (this “Agreement”) is entered by and between Martin Finkbeiner (“Executive”) on the one hand, and Western Digital Corporation (“WDC”), on behalf of itself and all other corporations or other entities a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by WDC (each, a “WDC Subsidiary”), on the other hand. WDC and all WDC Subsidiaries are referred to collectively herein as “Western Digital.”

WHEREAS, Executive has been employed by Western Digital as an Executive Vice President;

WHEREAS, Executive’s employment with Western Digital will terminate on December 1, 2010; and

WHEREAS, Executive’s execution and non-revocation of this Agreement is a condition of eligibility for Executive to receive severance benefits under the Western Digital Corporation Executive Severance Plan (the “Plan”).

NOW, THEREFORE, in consideration of the covenants undertaken and the releases contained in this Agreement, Executive and Western Digital agree as follows:

I. Separation. Executive and Western Digital hereby agree that Executive’s employment with Western Digital and his service as Executive Vice President, an officer, employee, and in any other capacity with Western Digital, shall terminate on December 1, 2010 (“Termination Date”). All payments due to Executive from Western Digital after the Termination Date shall be determined under this Agreement.

II. Final Compensation. On or before December 1, 2010, Executive shall receive payment for his accrued but unused vacation. Executive will continue to vest in outstanding equity grants through December 1, 2010. Executive shall submit his final expense report, if any, by December 1, 2010, which Western Digital shall reimburse in the ordinary business course. Executive is not required to sign this Agreement in order to receive the compensation, vesting and expense reimbursement described in this Section II.

III. Consideration. In the event that Executive executes (and does not revoke) this Agreement and complies with all of the terms herein, Executive shall be entitled to receive the benefits set forth below.

A. Lump Sum Payment. Western Digital shall pay to Executive the amount of One Hundred Fourteen Thousand Two Hundred Thirty Dollars and Seventy-Six Cents ($114,230.76), less standard withholding and authorized deductions. This payment shall be paid in one lump-sum payment within twenty-one (21) days following the expiration of the revocation period set forth in Section VI below.

B. Salary Continuation. Subject to the terms and conditions of this Agreement, for a period of twenty-four (24) consecutive months commencing on December 2, 2010 (the “Salary Continuation Period”), Western Digital shall pay Executive a salary continuation of Thirty-Seven Thousand Five Hundred Dollars and No Cents ($37,500.00) per month, less standard withholding and authorized deductions; provided, however, that such salary continuation obligation shall continue only for so long as Executive is in compliance with all provisions of this Agreement. Said salary continuation payments will be paid to Executive bi-weekly on Western Digital’s regular payroll cycle. All salary continuation payments due hereunder shall be paid by direct deposit to an account determined by Executive. Western Digital shall cease making any such salary continuation payments and shall have no further obligation to pay salary continuation to Executive at such time as (i) Executive is in material violation of any of the terms of this Agreement, or (ii) upon expiration of the twenty-four (24) month period, whichever occurs first. In addition, Western Digital will cease making any such salary continuation payments and shall have no further obligation to pay salary continuation to Executive on and after the date Executive is or becomes any of the following after the Termination Date: self-employed, or a partner or officer of, joint venturer with, employee of, or otherwise provides services (whether as a consultant, contractor, director or otherwise) for compensation (whether current, deferred, contingent or otherwise) to, any person or entity. Executive agrees to immediately notify Western Digital if he is or becomes so employed, provides such services, or otherwise has such a position or relationship. In the event Western Digital ceases salary continuation payments for any of the reasons specified herein, all other covenants undertaken and the releases contained herein shall remain in full force and effect. Notwithstanding the foregoing, in the event that a Change in Control occurs prior to the end of the Salary Continuation Period and Executive would be entitled to receive any salary continuation payments after the Change in Control date, such salary continuation payments will be paid to Executive in a single sum within ten (10) business days following the date of such Change in Control. For these purposes, “Change in Control” shall have the meaning ascribed to such term in Western Digital Corporation Amended and Restated Change of Control Severance Plan; provided, however, that a transaction shall not constitute a Change in Control unless it is a “change in the ownership or effective control” of WDC, or a change “in the ownership of a substantial portion of the assets” of WDC within the meaning of Section 409A of the Internal Revenue Code and the regulations promulgated thereunder.

C. ICP Bonus. Executive acknowledges and agrees that he has been paid all bonuses he is owed by Western Digital through the Termination Date. For the bonus cycle comprising the 1st Half of Fiscal Year 2011 (the period of July 1 — December 31, 2010), Executive shall receive a pro-rated bonus under the ICP in the amount of $159,897.52, less standard withholding and authorized deductions, which represents a payment equal to a pro-rata portion of Executive’s bonus opportunity under the ICP for the bonus cycle in which the Termination Date occurs, with such pro-rata portion based on the number of days in the applicable bonus cycle during which Executive was employed (153) and assuming 100% of the performance targets are met regardless of the actual funding by Western Digital. This payment shall be paid in one lump-sum payment within twenty-one (21) days following the expiration of the revocation period set forth in Section VI below.

D. Options. On the Termination Date, Executive’s then outstanding stock options will vest and become exercisable as if Executive had remained employed with Western Digital through June 1, 2011. Notwithstanding anything to the contrary herein, the exercisability of Executive’s outstanding stock options shall continue to be governed by the stock incentive plan and stock option agreement applicable to such options. Notwithstanding anything to the contrary herein, Executive shall not be entitled to any continued vesting under any stock option award following the Termination Date, and the Termination Date shall be deemed to be Executive’s “Severance Date” for purposes of any outstanding stock option award agreements.

E. Restricted Stock Units. On the Termination Date, Executive’s then outstanding and unvested restricted stock units will vest and become payable as if Executive had remained employed with Western Digital through June 1, 2011. Notwithstanding anything to the contrary herein, Executive shall not be entitled to any continued vesting under any restricted stock unit award following the Termination Date, and the Termination Date shall be deemed to be Executive’s “Severance Date” for purposes of any outstanding restricted stock unit award agreements.

F. Benefit Continuation. Provided Executive timely elects COBRA continuation of his medical, dental, and/or vision coverage existing as of the Termination Date and Executive complies fully with all terms of this Agreement, Western Digital shall make the applicable COBRA premium payments for a period of eighteen months beyond the expiration of Executive’s Company-provided medical, dental, and/or vision coverage existing as of the Termination Date (“COBRA Continuation”). Notwithstanding the foregoing, in the event Executive becomes eligible for equivalent coverage under another employer’s plan, Executive must immediately notify Western Digital of such eligibility and Western Digital’s obligation to continue COBRA premium payments pursuant to this Section III.F shall cease as of Executive’s benefit eligibility date. Executive understands that Executive remains responsible for working with Western Digital’s outside benefits administrator to elect COBRA benefits and must timely elect in order to be eligible for COBRA benefits.

G. Executive Outplacement. Western Digital shall pay for Executive to receive outplacement services provided by a vendor chosen by Western Digital for a period of up to twelve (12) months following the Termination Date, subject to a maximum cost to Western Digital of $25,000.

IV. General Releases. In consideration of the benefits set forth in this Agreement, and other good and valuable consideration, Executive on behalf of himself, his descendants, dependents, heirs, executors, administrators, assigns, and successors, and each of them, hereby covenants not to sue and fully releases and discharges Western Digital Corporation and each of its parents, subsidiaries and affiliates, past and present, as well as its and their trustees, directors, officers, members, managers, partners, agents, attorneys, insurers, employees, stockholders, representatives, assigns, and successors, past and present, and each of them (hereinafter together and collectively referred to as the “Releasees”), with respect to and from any and all claims, wages, demands, rights, liens, agreements, contracts, covenants, actions, suits, causes of action, obligations, debts, costs, expenses, attorneys’ fees, damages,

Executive represents that he has held all such information confidential and agrees he will continue to do so. Without limiting the generality of the foregoing, Executive agrees he will not, at any time, whether during or subsequent to the term of Executive’s employment with Western Digital, in any fashion, form or manner, unless specifically consented to in writing by Western Digital, either directly or indirectly, use or divulge, disclose, or communicate to any person, firm, or entity or corporation, in any manner whatsoever, any Confidential Material of any kind, nature or description concerning any matters affecting or relating to the business of Western Digital.

B. Use and Return of Confidential Material. Executive shall not, directly or indirectly for any reason whatsoever, disclose or use any such Confidential Material except in the course and scope of his employment with Western Digital, unless such Confidential Material ceases (through no fault of Executive’s) to be confidential because it has become part of the public domain or he is otherwise obligated to disclose such information by the lawful order of any competent jurisdiction. All records, files, drawings, documents, equipment and other tangible items, wherever located, relating in any way to the Confidential Material or otherwise to the business of Western Digital which Executive prepared, used or encountered, shall be and remain the sole and exclusive property of Western Digital and shall be included in the Confidential Material.
