To remove the hard drive, first remove the top cover. Pull on the green pull tab on the hard drive cable to carefully detach the hard drive cable from the hard drive. Note: Do not pull on the flat ribbon part
of the cable at any time. Detach the Phillips number two screw that secures the hard drive bracket to the chassis. Slide the bracket slightly toward the rear
of the unit, and pull the bracket assembly into the main cavity and out of the unit. To replace the hard drive, detach the four Phillips number two screws that secure the hard drive to the hard drive bracket. Lift the hard drive out of the hard drive
bracket. Before installing a new hard drive, first make sure that there are rubber grommets installed in each side hole of the hard drive bracket. Replace any missing rubber grommets. Place the hard drive spindle side down into the hard drive bracket. Secure the hard drive to the bracket with
the four Phillips number two flat-head screws. There is a tab at the front edge of the hard drive bracket that slides into a slot on the chassis. There are also two small holes on the hard drive bracket that slide over tabs on the chassis. There are also guides in the chassis to help align the hard drive bracket into the correct position. To replace the hard drive bracket assembly, place the hard drive assembly slightly to
the rear of its final location within the guides. Then slide the bracket forward until the tabs and slots have engaged. Secure the hard drive bracket to the PC with its Phillips number two screw. Carefully reattach the hard drive cable to
the rear of the drive. Do not use the flat ribbon part of the cable to handle the cable.
