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 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.
