Apple RAID: Disks Must Be Formatted by Apple RAID (11/94)


This article describes the need to format all hard drives to be used with Apple RAID with Apple RAID software rather that HDSC Setup.

To use a disk with Apple RAID, a disk must first be formatted by Apple RAID. This is because the size of the Apple RAID driver is substantially larger then the driver created by HDSC Setup. Because there is not enough space allocated at the beginning of a disk (given the current factory formatting for Apple disks), disks which are to be used by Apple RAID must be reformatted to make this additional space at the beginning of each disk.

Disks which have been formatted by Apple RAID are distinguished from non-Apple RAID formatted disks by using a different icon in the disk column of the Apple RAID setup window. For users who desire to use the Apple supplied disks with their PowerPC-based Workgroup Servers in a RAID array, each disk must be reformatted, and all System SW, applications and data will need to be reinstalled. Recommendations for how to do this will be included in the Apple RAID Users Manual.

WARNING: Formatting a hard disk will erase all data, be sure to backup any
drive before formatting it.
