Before any checks are performed, the program determines the number

one drive, you see this prompt each time you select a test:

Check which drive (A/B)?

Press

Enter.

If any errors occur, record the error

code and message and contact your dealer. Always have the diskette

drive serviced by your dealer or service center.

Sequential Seek Check

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 1.2MB, 720KB, and 1.44MB

diskettes.

Select option I 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 displays.
