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 Epson Customer Care 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 36OKB diskettes and track 79 for 720KB, 1.2MB, and 1.44MB 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 program counts the track numbers 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 reappears.

Random Seek Check

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.
