When to use the Low-Level Format program

Preparing the hard disk drive for use

Notes:
1. The low-level format is not available on all diagnostic diskettes.
2. Before formatting the hard disk drive, make a backup copy of the files on the drive to be
formatted.
Use the Low-Level Format program in the following situations:
• When you are installing software that requires a low-level format.
• When you get recurring messages from the test programs directing you to run the
Low-Level Format program on the hard disk.
• As a last resort before replacing a hard disk drive.
When the Low-Level Format program is finished, restore to the hard disk all the files
that you previously backed up.
1. Partition the remainder of the hard disk for the operating system. (The commands
vary with the operating system. Refer to the operating system manual for
instructions.)
2. Format the hard disk using the operating system. (The commands vary with the
operating system. Refer to the operating system manual for instructions.)
3. Install the operating system.
You are now ready to restore the files.
