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.
