If you have only one floppy disk drive, you are prompted to change the
diagnostics diskette for a blank diskette before running the test. You see these
messages:
Use only a formatted blank diskette for this
test.
Any data present may be erased.
If using drive A,
remove your Diagnostics Disk.
Enter Y to start this check.
Enter N to return to the menu.
Make sure the blank diskette you prepared is in drive A, then press
Y
and
Enter.
The program displays the current track number as each cylinder is
tested. For example, with a 720KB floppy disk, the first message you see is:
Current track is

Speedcheck
This test checks the revolution speed of the specified disk drive. Select
option 4 from the menu to start this test. You see a message similar to this:
The disk rotation speed should be more than
294.0 rpm and less than
306.0
rpm.
The computer spins the diskette for a few seconds then displays a
message like this:
The disk rotation speed is now
300.0
rpm.
Note:
The speed for a 360KB or 720KB (3½-inch) drive should be 300 rpm.
This check permits a tolerance of ± 2%.
The diskette continues to spin,
and the disp1ay is updated every few
seconds. To stop the test, press any key; the program returns to the menu.
If you try to perform a speed test without inserting a floppy disk, 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.
