Select option 1 from the menu to start this test. The program
displays the number of each cylinder it finds, counting down to 0.
The seek is performed by the read/write heads simultaneously, so
you see the cylinder numbers only once. If no errors occur, the
menu is redisplayed.
Write, Read Check
This check tests the ability of the hard disk drive to read and write
data. The test writes to and reads from each sector of the innermost
cylinder of the disk, using each head.
N o t e
This test destroys all data on the innermost cylinder of the hard
disk drive. This cylinder is reserved for diagnostics, however, and
is never used for storage by MS-DOS. Therefore, data created by
MS-DOS is not destroyed.
Select option 2 from the menu to start this test. You see this
message:
The data on the highest physical
cylinder
may
be destroyed by this check.
Enter Y to start this check.
Enter N to return to the menu.
Press Y and then
Enter
to continue the test.
You do not see a cylinder count during the test. If no errors occur,
the program returns to the menu.
If an error is reported, make a note of the code and message. Then
consult your dealer.
Read, Verify Check
This test reads and verifies data from all tracks of the disk, checking
each cylinder and using all heads.
