Format a disk.

-
Any existing data is destroyed when you reformat a disk.
-
The need for formatting a disk drive has decreased as more
and more manufacturers ship their disk drives formatted and partitioned. You
might not need to use the format utility when you add a
disk drive to an existing system.
-
If a disk has been relocated and is displaying many disk errors,
you can attempt to reformat it. Reformatting automatically remaps any bad
sectors.

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.
-
The repair of a disk drive usually means that a bad sector
is added to a defect list. New controllers remap bad sectors with no system
interruption.
-
If the system has an older controller, you might need to remap
a bad sector and restore any lost data.
