If necessary, use a program such as DOS-Debug or
Speedstor to perform a low-level format of the disk.
Many computers also have a format utility included in the
BIOS setup; check the hardware manual for your
computer.
WARNING:
A low-level format destroys all information currently stored
on a hard disk.
Many ESDI and SCSI disk controllers have on-board
BIOS routines.
You can use these routines to perform a low-level format of your disk:
Boot DOS.
At the DOS prompt, enter:
debug
Depending on your disk controller,
enter one of the following commands
at the ``-'' prompt:
for Adaptec SCSI controllers:
g=dc00:6
for ESDI controllers:
g=c800:5
See your computer and/or controller documentation for more details.
