Epson 100 Manuel D’Utilisation

Before it performs any checks, the program determines the

number of diskette drives installed in your computer. If you
have more than one drive, you see this prompt each time you

select a test:

Check which drive (A/B)?

Press A or B and then Enter. If any errors occur, record the

error code and message and contact your Customer Care
Center.

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

part of the diskette. This action by a read/write head is called a

seek. During this test, each head seeks sequentially from the

innermost track to the outermost track. The innermost track is

track 39 for 360KB diskettes and track 79 for 720KB diskettes.

Select option 

1 

from the menu to start this test. The program

displays the number of each track it finds. For example, with a

360KB diskette, the first message you see is:

Current track is 39

The track number counts down (from 39 or 79) to 0. The seek

is performed by each head, so you see the count twice. If no

errors occur, the menu reappears.

This test is identical to the sequential seek check, except that

the seek operation is performed on each track in random order

instead of sequential order. Select option 2 from the menu to

start this test.
