[. . . ] The hard disk drive is either a Serial ATA (advanced technology attachment) drive that uses a narrow data cable, or a Parallel ATA drive that uses a wide data cable. CAUTION: Back up your personal files on the hard disk drive to an external storage device, such as a CD, before removing the hard disk drive. Failure to do so will result in data loss. After replacing the hard disk drive, you need to run System Recovery, using the recovery discs, to load the factory-installed files. See the user documentation that came with your PC for details about the recovery procedure. Locating Components Inside the PC You can add an optical drive into an empty lower optical drive bay. IMPORTANT: Before adding a new optical drive, make sure that it is compatible with the Microsoft® Windows® XP operating system. Also, make sure you have the correct software and drivers for the optical drive to work with the operating system.

You need these screws to install the new drive. 5 Slide the drive partway into the drive bay, making sure to align the guide screws with the guide slots. Replacing or Adding a Drive 1 If necessary, remove the existing drive. See "Removing a Drive" on page 3. 2 If you are adding a drive to an empty lower optical drive bay, you must remove the blank plate from the bay. To do so, insert a flat screwdriver into the blank plate slot (C) and rotate the screwdriver to break the blank plate out of the chassis. Discard the blank plate. 6 Reconnect the power and data cables to your drive, as indicated in the following illustrations. If it is present, reconnect the sound cable. 3 Make sure the jumper on the new optical drive or new Parallel ATA hard disk drive is in the CS (Cable Select) position. Your drive may vary from the illustration. The Serial ATA hard disk drive does not use cable select. Connecting the Optical Drive Cables NOTE: An optical drive may include a sound cable. Connect this cable also. Cable Select Jumper 4 Install four guide screws on the sides of the new drive (two on each side). The screws help guide the drive into its proper position in the bay.
