  At meetings with investors and analysts this week, executives of Western Digital Corporation (the "Company") will provide updates regarding current conditions in the hard drive industry, its plans for future wafer fabrication capacity additions, and shipments of its newest PMR-based 2.5 inch products. Specifically, the Company expects to communicate the following:<br><br>&#x2022;  As expected, demand and pricing in the hard drive markets thus far in the June quarter are seasonally soft.<br><br>&#x2022;  Historically, June quarter shipment patterns are more back-end loaded than other quarters. As a result, business in the remainder of the quarter will determine the Company&#x2019;s June quarter financial performance.<br><br>&#x2022;  Weeks of inventory in the distribution channel for the industry and for the Company are within the long-stated manageable range of 4 to 6 weeks.<br><br>&#x2022;  The Company has finalized plans for expanding its head wafer fabrication capacity. Specifically, the Company currently expects to spend approximately $200 million in its fiscal year 2008 and approximately $100 million in each of the subsequent two fiscal years, for a total of approximately $400 million for this purpose over the three-year period. The expansion involves additions to the Company&#x2019;s existing head manufacturing facilities.  These investments are incremental to the Company&#x2019;s normal capital expenditures levels.  Previously, the Company had indicated that the wafer fabrication expansion could require a new facility and the expenditure could total as much as $800 million.  <br><br>&#x2022;  In a separate press release today, the Company announced it is now shipping the new 250 GB WD Scorpio&#x2122; 2.5-inch Serial ATA hard drive for notebook PCs, one of the industry&#x2019;s fastest growing markets. The drives utilize the Company&#x2019;s own perpendicular magnetic recording (PMR) technology to achieve the industry&#x2019;s highest capacity in a small form factor drive and have WD proprietary features that make the drive quiet, use less power and run at cool operating temperatures. The WD Scorpio 250 GB hard drive is a result of the significant investments the Company has made in proprietary head technologies as well as significant system level feature innovation.<br>
