2.Remove the hard-disk drive.

To install a replacement hard-disk drive, perform the following steps.

CAUTION: Before you remove the computer cover, see "Precautionary Measures."

1.If you are replacing a hard-disk drive that contains data you want to keep, be sure you have a backup of your files before you begin this procedure.

2.Prepare the replacement drive for installation.

NOTICE: Wear a wrist grounding strap or ground yourself by touching an unpainted metal surface on the back of the computer.

NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage the drive. Instead, set the drive on a surface such as a foam pad that will sufficiently cushion it.

Check the documentation for the drive to verify that it is configured for your computer system.

3.Remove the computer cover as instructed in "Computer Cover."

4.Remove the drive bracket from the chassis as instructed in "Hard-Disk Drive Bracket Removal."

5.Slide the drive into the chosen bay of the bracket, oriented so that the connectors on the back of the drive will face the back of the chassis when the bracket is reinstalled (see Figure 16).

6.Align the four screw holes of the drive and bracket. Insert and tighten the screws (see Figure 17).
