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. For example,
with a hard disk, the first message you see is:
Current cylinder is nnn
The cylinder number counts 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 reappears.
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.
Note:
This test destroys all data on the innermost cylinder of the selected
hard disk drive. This cylinder is reserved for diagnostics, 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 these messages:
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 with 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 occurs, make a note of the code and message. Then use the
N o n - d e s t r u c t i v e s u r f a c e a n a l y s i s ( o p t i o n 4 o n t h e H A R D D I S K
FORMAT MENU) to check the condition of the hard disk.
