Enter selection number:

Before any checks are performed, 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 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.
