Epson 10020 Manuel D’Utilisation

When you select option 17 from the DEVICE LIST, you see
this menu:

HARD DISK DRIVE(S) AND CONTROLLER CHECK MENU

1 - Seek check

2 - Write, read check

3 - Error detection and correction check

4 - Read, verify check

5 - Run all above checks

0 - Exit

Enter selection number:

If you specify to run the hard disk drive check multiple times,
this menu does not appear and only the first three tests are

performed.

When you select a check from this menu, the program

determines the number of hard disk drives installed in your

computer. If you have more than one drive, each time you
select a test you see this prompt:

Check which drive (C/D)?

Press C or D and then Enter.

This test checks the ability of the read/write heads to locate any

part of the hard disk. This action by a mad/write head is called a

seek. During this test, each head seeks each cylinder of the disk

in sequence, starting from the center.

Select option 1 from the menu to start this test. The program
displays the number of each cylinder it finds, counting down

from 614 (for a 20MB hard disk) to 0. The seek is performed by

the read/write heads simultaneously, so you see the cylinder

numbers only once. If no errors occur, the menu reappears.
