check
If you specified to run the hard disk drive check multiple times, this
menu does not display 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, then each time you select a test you see this prompt:
Check which drive (C/D)?
Press C or 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 read/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 is displayed.
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.
