When you
Setup menu, you see this screen:
The three options listed on the bottom half of the screen are
hard disk diagnostic tests. These tests are destructive in that
they destroy data on the hard disk. Therefore, if possible, be
sure to back up any data on your hard disk before performing
these tests.
Hard Disk Fornat
The hard disk in your computer has already been formatted for
you. You need to reformat this hard disk only if you have a
serious problem with the drive. However, before formatting a
disk with data on it, try every other recovery procedure
described in your operating system manuals. Then, if possible,
back up all the data on the disk before you begin.
You must still partition and format the hard disk for the
operating system after performing this low-level format. See
your operating system manuals for instructions.
