Format a disk
|
-
Any existing data will be destroyed when a disk is reformatted.
-
The need for formatting a disk drive has dropped
as more and more manufacturers ship their disk drives formatted and partitioned.
You might not need to use the format utility when adding
a disk drive to an existing system.
-
If a disk has been relocated and is displaying
a lot of disk errors, you can attempt to reformat it, which will automatically
remap any bad sectors.

Divide a disk into slices

-
Any existing data will be destroyed when a disk with existing
slices is repartitioned and relabeled.
-
Existing data must be copied to backup media before
the disk is repartitioned and restored after the disk is relabeled.

Repair a disk drive
|
-
Some customer sites prefer to replace rather than repair defective
drives. If your site has a repair contract with the disk drive manufacturer,
you might not need to use the format utility to repair
disk drives.
-
Repairing a disk drive usually means that a bad
sector is added to a defect list. New controllers remap bad sectors automatically
with no system interruption.
-
If the system has an older controller, you might
need to remap a bad sector and restore any lost data.
