Read, Verify Check
This test reads and verifies data from all tracks of the disk,
checking each cylinder and using both heads.
Select option 4 from the menu to start this test. The program
displays the number of each cylinder it finds. For example, with
a 20MB hard disk, the first message you see is:
Current cylinder is 614
The cylinder number counts down to 0.
At the end of the test, you see a table of the results of the test.
For example, for a 20MB hard disk with no bad tracks, you see:
BAD TRACKS
..............
0
READ ERROR TRACKS
.......
0
GOOD TRACKS .............
2460
Press ENTER to return to the menu
Press
Enter
when you have viewed the table.
If the results show BAD TRACKS on your disk, it is all right
because those tracks will not be used. If, however, the results
show any READ ERROR TRACKS, run the Destructive
surface analysis described in Appendix D.
Run All Above Checks
To run all the tests on the menu in sequence, press 5 and then
Enter. When you choose this option, all checks for the hard
disk drives 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.
