The Adaptec BIOS has on board utilities for doing a low-level format
of a SCSI drive. Although they are not really needed, except in some
strange cases. All SCSI hard drives come pre-formatted at the fastest
interleave the drive will support. The only time you would need to do a
low-level format is if you picked up a bad block on a device, or a drive
came with a partition table already installed on it.
In some cases, such as the Quantum drives, it does no good to format them.
The Quantum drives will not do a low-level format. They just accept the
command and return good status. They do this as they are hard sectored
and more SCSI drives are coming out this way.
