Removing the CD Drive—Small Mini-Tower Computer
CD Drive Replacement
1. If you are replacing a drive that does not have the bracket rails attached, remove the rails from the old drive by
removing the two screws that secure each rail to the drive. Attach the bracket to the new drive by aligning the screw
holes on the drive with the screw holes on the bracket rails and tightening all four screws (two screws for each rail).
2. If you are installing a new drive, connect it to the set of rails that are attached to the inside of the cover.
If a set of rails is not attached to the inside of the cover, contact Dell.
