If one of your hard disk drives is already installed in the
computer, follow the steps under “Removing a Hard Disk
From the Vertical Position” on page 7-17 to remove it. Then
set the jumpers on both drives while they are out of the

Note
If you are removing one hard disk drive and leaving one in
your computer, be sure to set the jumpers on the
