More expensive drives will write new sector headers. Most new drivesSCSI drives
have embeded serveo so you don't have a dedicated area for the servo
information. This allows the distk to be written (where convenient) during
a low-level format. Subsequent reads and writes will serve o to the center
of the newly created tracks. This means that you can't do anything bad
to the drive by low-level formatting it. Of course you eliminate any
data that had been present.
If you low-level format a SCSI Drive, it would be advantageous to
do the following:
(1)
Mount the drive in its final position.
(2) Pust all the pieces of you machine r machine back together.
(3) Let the drive warm up for several hours.
(4) THEN format the drive.
(5) If the format utility has a bad-block scan, exercise this also.
Bad blocks will be aotomaticallyutomatically relocated. If not, temporarily
partition and format it with DOS. MS-DOS reads the entire disk drive
during its high-level format. This will force bad blocks to be reloated.
(6) Then do you r Linux FS building.
