Western Digital (250-0100/1/2/3/4) Features Faxback Doc. # 5714 Hard Disk Upgrade Kits The Western Digital Caviar AT-IDE drives are suitable as new, upgrade, or replacement drives for installation in your IBM PC/AT or compatible system. The Caviar hard drive is an IDE drive. It does not require a separate controller card if your system provides a 40-pin IDE connector on the motherboard or add-in board. Because of its compact size the Caviar drive can be incorporated into the newest generation of desktop and PC/AT systems. The Caviar hard disk is a 3.5 inch drive that can also be used in a 5.25 inch drive bay with a 5.25 inch frame which is included. Your IDE drive is low-level formatted and defect free. Although you can use your Caviar drive with Disk Operating System (DOS) version 3.0 or later, Western Digital recommends upgrading to Dos version 5.0 or later. Automatic Head Park The Caviar drive provides an automatic feature that parks the drive heads when the system power is turned off. No separate utilities are required to park the Caviar drive. If you move your system, be sure to turn the system power off. The drive heads are then automatically moved to a safe, non-data area, and the heads are locked into place. This helps protect the disk media and the heads from accidental damage due to vibration, moving, or shipping. (SMC/jlc-08/08/94)
