If you specify to run the hard disk drive check multiple times,
this menu does not appear and only the first three tests are
performed.
When you select a check from this menu, the program
determines the number of hard disk drives installed in your
computer. If you have more than one drive, each time you
select a test you see this prompt:
Check which drive (C/D)?
Press C or D and then Enter.
Seek Check
This test checks the ability of the read/write heads to locate any
part of the hard disk. This action by a mad/write head is called a
seek. During this test, each head seeks each cylinder of the disk
in sequence, starting from the center.
Select option 1 from the menu to start this test. The program
displays the number of each cylinder it finds, counting down
from 614 (for a 20MB hard disk) 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 reappears.
