Removing and Replacing Drives Your computer has several drives that you can replace or upgrade. See "Locating Components Inside the Computer" on page 7 for the drive types and locations. The hard disk drive is either a Serial ATA (advanced technology attachment) drive, which uses a narrow data cable, or a Parallel ATA drive, which uses a wide data cable. Select models have a second hard disk drive. CAUTION: Before you remove the hard disk drive, back up your personal files on the hard disk drive to an external storage device, such as a CD. Failure to do so will result in data loss. After replacing the hard disk drive, you must run System Recovery using the recovery discs to load the factory-installed files. For details about the recovery procedure, see the user documentation that came with your computer. 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 operating system.
