Select option 3 from the menu to start this test. The program
displays the number of each cylinder it finds. The first message you
s e e i s :
Current cylinder is nnn
The cylinder number counts down to 0. At the end of the test, you
see a table showing the results of the test. For example, if your hard
..
disk has three bad tracks, you see:
BAD TRACKS . . . . . . . . ...3
READ ERROR TRACKS . . ..0
GOOD TRACKS . . . . ...2457
Press
Enter
to return to the menu after viewing the table. Don’t
worry if there are some bad tracks on the disk. They have been
marked by the manufacturer and are not used to store data.
Run All Above Checks
To run all the tests on the menu in sequence, press 4 and then
Enter.
When you choose this option, all checks for the hard disk drive and
controller are performed automatically in sequence, Although you
do not start each test, you must still supply the appropriate
responses to progress from one test to the next.
When you see a prompt warning you that the data on the highest
physical cylinder may be destroyed, press Y and then
Enter
to
continue with the test. (The highest numbered cylinder is reserved
for diagnostics and is never used for storage by MS-DOS. Therefore,
data created by MS-DOS is not destroyed.)
Alternate Parallel Port Check
Use this option to test the functions of an additional parallel port.
To perform the test, you must insert a special loop-back connector
into the alternate parallel port so that the computer can check the
port’s individual pins.
