Low Level Format
format program (referred to as a low-level format), is different from the
operating system format program. The operating-system format program will
not erase the System Partition; the low-level format program will.
It also will erase the system programs and completely clear the hard disk.
If the hard disk is working, make a backup copy of the System Partition
and all the files on the hard disk before you use this program. (If you
do not know how to make a backup copy of the System Partition, see "Backing
up the System Partition" in topic 2.10.4.) To backup all of the files,
see the operating system
documentation. (It might take up to two hours to run the low-level
format program, depending on the disk capacity.)
When to Run the Low-Level Format Program
There are three reasons to run this program:
1.You are installing software that requires a low-level format.
2.You get recurring messages from diagnostic tests telling you
to run the low-level format program on the hard disk.
3. A last resort before replacing a failing hard disk drive.

1.Power-on the computer.
2.Start the system programs (Starting
3.When the Main Menu appears, press Ctrl+A.
4.When the Advanced Diagnostic Menu appears, select Format Hard
Disk. Then, follow the instructions on the screen.
Preparing the Hard Disk for Use
When the low-level format program completes, you must copy all the
files to the hard disk. Before you can copy the files, you must:
1.Create the System Partition (if the hard disk drive had a
System Partition) using the Restore
the System Partition utility program from the system programs on the
2.Format the hard disk using the operating system. (The commands
vary with the operating system. Refer to the operating system manual for
a description of the program commands to use.)
3.Install the operating system.
You are now ready to reinstall the files.
