Ultra ATA Drive Guidelines and Features The attach sequence rule may also be stated in table format: General Attach Sequence Rule* Sequence Description 1 The lowest class drive - bootable hard drive recommended. 2 If only two drives, the last drive goes here; otherwise the lowest class of the remaining drives. 3 If only three drives, attach the final drive here. If a fourth drive exists, attach the lowest class drive here. 4 If there is a fourth drive, attach the final drive here - the drive with the highest class number of all devices. *If there are three or more devices, two or more of which are hard drives, two hard drives should be attached to the primary controller first before following the General Attach Sequence Rule. The rules allow for: ■ Keeping the hard drive on a separate controller channel maximizes drive performance until a fourth device is added. ■ Keeping the hard drives and removable media drives on separate controller channels maximizes compatibility. ■ Keeping the hard drive and the writable optical drive on separate controller channels maximizes optical drive reliability. 4.3.3 Attach Sequence Worksheet Use the worksheet below for obtaining optimum system performance when setting up a computer with multiple drives.
