5.25-inch Drive 1. Prepare the computer for disassembly (Preparation for Disassembly on page 56). 2. Remove the access panel (Access Panel on page 57). 3. Remove the front bezel (Front Bezel on page 58). 4. Disconnect the power and data cables from the back of the drive. 5. Remove the two retainer screws that secure the drive to the bay (1), and then slide the drive forward and out of the bay (2). To install a drive, reverse the removal procedure. Be sure to install a guide screw on the front right side of a new drive. The guide screw helps secure the drive in place. NOTE: If you are installing a drive in the bottom 5.25-inch drive bay, remove the metal shield that covers the bay by pressing inward on the silver tab on the left side of the chassis then pulling the shield out from the front of the chassis. There are a total of eight extra guide/retainer screws on the front of the chassis behind the bezel. Four have 6-32 standard threads and four have M3 metric threads. Standard screws are used for hard drives and have a silver finish. Metric screws are used for all other drives and have a black finish. Be sure to install the appropriate guide screws into the drive.
