hard drive. You do not have to select Clear to erase existing information on your SCSI disks, such as a DOS partition. That information is erased when you
initialize logical drives.
Rebuilding Failed Hard Drives
If a hard drive fails in an array that is configured as a RAID 1, 5, 10, or 50 logical drive, you can recover the lost data by rebuilding the drive.

NOTICE:

drive has a higher logical drive number than the drive you want to delete.
