Epson LT-286e User Manual

This test checks the sequential seek, read, and write capabilities
of a floppy disk drive. It performs a sequential read/write

operation on the diskette in the specified drive.

To perform this test, insert a diskette into the drive you plan to

test. Use a diskette you have formatted with the Diskette
Format test.

This test destroys all data on the diskette.

This test checks the status of the disk change line. This line

should change when you insert or remove a diskette from a
floppy disk drive.

To perform this test, insert a diskette into the drive you plan to

test. Use a diskette you have formatted with the Diskette

Format test.

DIAG displays two types of error messages while testing the

floppy disk drive: messages DIAG generates and those the

controller generates.

DIAG may display the following error messages during the Disk

Change Line test:

W a r n i n g   - Change 

line inoperational

DIAG displays this message if the line is not working
properly. This may indicate a problem exists with the floppy
drive or the controller.
