Epson 4SLC2-50 - Manual (Page 90)

When
you select the HARD DISK UTILITY from the main 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 Format
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, backup 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.
