Epson LT - 286e - Manual (Page 29)

Start and end head numbers
DIAG displays the following prompts for the starting and
ending head numbers:
Start Head number ?
End Head number ?
Enter the first and last head numbers on which you want to
perform the tests. The default for the start head number is 0,
and the default for the end head number is one less than the
highest head number of your hard disk. The highest head
number for the Equity LT-286e is 3.
After you specify the hard disk parameters required for the
selected diagnostics test, DIAG begins executing the test.
Hard Disk Format
Use this test when installing a new hard disk in your computer.
It preformats your hard disk on the hardware level. (You must
still format the hard disk for your operating system.)
You may need to reformat a hard disk if you have a serious
problem with the drive. However, before executing this program
on a hard disk with data, try every other recovery procedure
described in your operating system manual. Then back up all
data on the hard disk before you start the DIAG program.
The Hard Disk Format program lets you format the entire hard
disk or any portion of it.
