1 Investor Relations: Bob Blair Western Digital Corporation 949.932.7834 bob.blair@wdc.com Public Relations: Steve Shattuck Western Digital Corporation 949.932.5178 steve.shattuck@wdc.com FOR IMMEDIATE RELEASE: WESTERN DIGITAL ANNOUNCES FOURTH QUARTER YEAR END RESULTS IRVINE, Calif. -- July 27, 2000 -- Western Digital Corporation (NYSE: WDC) today reported revenues of $473.9 million and a proforma net loss of $26.3 million, or $.19 per share, for its fourth quarter ended June 30, 2000. For the same period, on a GAAP basis, Western Digital reported net income of $4.2 million and earnings per share of $.03. The total results for the quarter included non-recurring benefits for tax and other accrual adjustments of $30.5 million, $11.0 million of which was included in selling, general and administrative expenses. In the year-ago period, the Company reported revenues of $709.3 million and a proforma net loss of $81.5 million, or $.90 per share. The total net loss for the year-ago period was $101.5 million, or $1.12 per share, and included a restructuring charge of approximately $20 million for the sale of the Company's media business. Matt Massengill, president and chief executive officer, stated: "Both our fourth quarter and year-over-year results reflect substantial progress at Western Digital in a challenging industry

2 Western Digital Announces Fourth Quarter Year End Results Page 2 environment. Price competition in the June quarter was significant and the non-linear supply of microprocessors led to fewer desktop PCs being shipped in the quarter than otherwise would have been the case. Nevertheless, the reductions in operating expenses and manufacturing costs we implemented over the last year enabled us to mitigate our operating loss for the quarter. Thus far into the September quarter, we have seen signs of healthier demand as availability of microprocessors has improved and our recovery of business with major PC OEM customers continues, albeit at prices impacted by the June quarter activity. "For the year, we are pleased with the significant progress made by the WD team on many fronts in the core HDD business," said Massengill, noting: - Closing the gap on competitive gross margin performance, moving from negative gross margins in Q1 to near double-digit performance in the second half of fiscal 2000; - Increased market share with major PC OEM customers, based on solid and sustained time-to-market performance and supply chain management expertise; - Technology leadership with time-to-market WD Caviar(TM) 7200 RPM hard drives, including shipment of its first Ultra ATA/100-enabled 7200 RPM hard drive in the June quarter. 7200 RPM hard drives accounted for 32% of the company's units shipped in the fourth quarter, up from 20% in the March quarter; - Reduction of nearly 30%, or $106 million, in operating expenses; - Successful consolidation of three manufacturing operations into a single highly-efficient site in Kuala Lumpur, Malaysia; and - Improved asset management, including a combined 10-day decrease in receivable and inventory days from the fourth quarter of 1999. -MORE-

The selection of the WD Performer(TM) 15i hard drive by Microsoft WebTV Networks, Inc. for use in its Ultimate TV service was a major validation of WD as a player in this space," continued Massengill.
