The Company expects revenue of approximately $530 million and a net loss between $7 million and $10 million, or $.04 to $.06 per share. These results will include a net operating profit from its hard drive business between $6 million and $8 million on unit shipments of just over 6 million. The new estimates are an improved outlook from the Company's previous guidance for the March quarter as stated January 25, 2001. At that time, the Company estimated that its March quarter revenue would be no less than $500 million and its operating loss would range between $13 million and $17 million or $.07 to $.10 per share. Final results for the third quarter will be reported after the market closes April 26, 2001.

2 The Company credits its better-than-expected Q3 performance to solid product position with customers and better-than-expected product mix and pricing dynamics. The Company also reduced spending on new-venture businesses in Q3 more than it had previously anticipated. "Despite a difficult PC market worldwide, our focus on time-to-market execution in both the 7,200 RPM and 5,400 RPM product segments provided the opportunity for sequential unit volume growth, while achieving better-than-anticipated gross margins," Matt Massengill, Western Digital president and chief executive officer, said. "This execution, combined with improved industry inventory management practices, is resulting in improved profitability for Western Digital's hard drive business."
