the bar cursor. Then, press < ENTER > . That causes the
Hard Disk Test Cylinder Test box to appear on the left side of
the screen. The box contains the following questions (fields)

responses are addressed earlier in this tab under the heading

If you want to change a response to one or both of these fields
before running the test, enter N at the "Proceed" field. This
will return the cursor to the Disk Drive Type field unless the

CMOS Setup screen. If this has not been done, the cursor will
prompt you for an appropriate response at this field first.
After you have entered the appropriate information at the first
two fields, enter "Y" at the "Proceed" field.
This causes the Activity box to appear on the right side of the
screen. The words "Write" and "Verify" are highlighted in the
upper half of the box. These flash while the test is in progress

lower half of this box, the status line displays the number of
the last cylinder in the hard disk, the number of the the last
head, and the sectors in sequence as they are tested. When this
test is aborted or finished, press < ENTER > to return to the
