David, If you haven't had the chance to read the data file that was suggested earlier, this is what you need to look for. At the IDE ribbon end of the hard drive mounting plate, you can see a very small screw with a flat head that is holding the plate to the chassis. This screw must be taken out before you can remove the drive and/or the mounting plate from the G4. Once the screw is removed, the mounting plate must be pulled toward the case hinge to unhook two tabs from their slots in the chassis. Turn the mounting plate over to see the tabs and the screws holding the drive to the plate. When you re-install the plate, be sure that you mount the drive on the plate facing in the proper direction (circuit board toward the plate and the IDE/power connectors toward the case hinge. You can verify your alignment prior to tightening the mounting screws. Hope this helps, Ron
