Epson Y16499100301 User Manual

When you finish running the floppy disk drive check, press

0 and 

Enter 

to return to the OPERATION MENU.

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 79 for 720KB diskettes and track

39 for 360KB diskettes.

Select option 1 from the menu to start this test. The

program displays the number of each track it finds, counting

down from 79 or 39 to 0.

The seek is performed by each head, so you see the count

twice. If no errors occur, the menu is displayed.

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.

This test checks the ability of the selected disk drive to

read and write data from a diskette. The test writes to and
reads from each cylinder on the diskette, starting at the center.

This test destroys all data on the diskette in the selected drive.

Select option 3 from the menu to start this test.

If you have only one diskette drive, you are prompted to

replace the reference diskette with a blank diskette before
running the test. You see the following messages.
