You may see the following message if you attempt to run the

Change line test on a drive that does not support a change line,

such as a 360KB or 720KB drive:

Change line not available

The controller displays one of these messages when an error
occurs during a diagnostics procedure:

Bad address mark

Bad CRC error
Bad DMA error
Bad seek error

Diskette write protected

Media change error

Record not found

Timeout error

These errors could occur because of a faulty drive, controller, or
cable, or if you attempt to run a test on a write-protected or
unformatted diskette.

These tests are listed in the Miscellaneous diagnostics submenu

to 

provide a complete check of the parallel and serial ports:

Printer adapter test

Comm. adapter test

This test checks the parallel port and the printer by sending a

pattern to the printer. If the printer does not print the pattern,

the test has failed.
