Adding a Second Hard Drive
CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions on page 9.
CAUTION: To guard against electrical shock, always unplug your
computer from the electrical outlet before opening the cover.
NOTICE: To avoid damage to the drive, do not set it on a hard surface.
Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
1 Check the documentation for the drive to verify that it is configured
for your computer.
2 Perform an orderly computer shutdown using the operating system
menu.
3 Turn off your computer and any devices.
4 Ground yourself by touching an unpainted metal surface on the
chassis, such as the metal around the card-slot openings at the back of
the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the
computer chassis to dissipate any static electricity that might harm
internal components.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network wall jack.
5 Disconnect your computer and devices from their power sources. Also,
disconnect any telephone or telecommunication lines from the
computer.
6 Disconnect the computer power cable from the wall outlet, and then
press the power button to ground the system board.
7 Open the computer cover (see page 83).
8 Remove the two green plastic rails from the inside of the hard-drive
bay by gently pulling the rails up and out of the bay.
9 Attach the rails to the hard drive using the two screws attached to the
rails.
Ensure that the rail tabs are positioned at the back of the hard drive.
NOTICE: Do not install any drive into the lower hard-drive bay until you have
removed the green drive rails from the inside of the hard-drive bay.
