Installing the Drive
Follow these steps to install a drive in the upper or lower
external drive bay:
1. Using a screwdriver, reach inside the back of the drive bay
and insert the screwdriver into one of the holes in the metal
plate covering the drive bay slot. Move the screwdriver up
and down until the plate loosens; then grasp the plate with
your hands and pull it out of the back of the drive bay.
Discard the plate; you do not need to reinstall it.
2. Remove the plastic faceplate from the bay by pushing it out
from the inside of the computer.
Keep the faceplate in a safe place in case you remove a drive
later (or if you install a hard disk drive).
