Installing a Hard Drive
1 Unpack the replacement hard drive, and prepare it for installation.
2 Check the documentation for the drive to verify that it is configured for your computer.
3 If your replacement hard drive does not have the bracket rails attached, remove the rails from
the old drive by removing the two screws that secure each rail to the drive. Attach the bracket
rails to the new drive by aligning the screw holes on the drive with the screw holes on the
bracket rails and then inserting and tightening all four screws (two screws on each rail).
