Note
Be sure to insert a blank diskette that has been formatted before you run the Diskette format test. Then use that diskette when you run any of the other destructive tests. Check that you have inserted the correct diskette before you press [vl at the Proceed prompt.
You see the following prompt before the program performs a test:
Diskette drive (A/B) ?
If necessary, type the drive identifier and press m. (If you have only one diskette drive, drive A is already entered for you.) Press [VI and m at the Proceed prompt to begin the test. Press [Nl and m to return to submenu.
Note
When you are finished running any of these tests on the test diskette, you must reformat it before you can use it.
Floppy Disk Error MessagesThe diagnostics program displays two types of error messages while testing a diskette drive: messages the program generates and those the controller generates.
The program may display the following error message during the Disk change line test:
Warning - Change line inoperational
This message appears if the line is not working properly and may indicate a problem in the drive or its controller.
