Last time we had a drive do that, when we opened it up, there was the distinctive groove where the head had crashed. It keeps making noises cause it tries and fails to reset the head properly. Hopefully you have recent backups. If you have a spare drive of the same make and model, swapping the electronics is a fairly trivial task. A couple of screws and a connector.
