If you try to perform a speed test without inserting a diskette, or if a read error occurs, you see this message and prompt:

Disk is defective or not installed properly. Press ENTER to return to the menu.

Disk Change Check

This test checks the ability of the diskette drive to detect that a diskette has been removed or inserted.

Note

Disk changes cannot be detected by 360KB 5 1/4-inch drives.

Select option 5 from the menu to start this test. You see the following message:

DISK CHANGE CHECK

Remove the disk from drive A.

As soon as you remove the diskette, you see the following message:

Re-insert the disk into drive A.

Re-insert the diskette. If no errors occur, the menu reappears. An error occurs if the drive is malfunctioning or if you do not remove or replace the diskette within a certain time.

Run All Above Checks

To run all the tests on the menu in sequence, press 6 and Enter.

When you choose this option, all checks for the diskette drive(s) and controller are performed automatically in sequential order. Although you do not start each test, you must still supply the appropriate responses to progress from one test to the next.
