The drive is Barracuda 7200 1.5 TB SATA. It was in an external enclosure when it was dropped. The motor is seized up and when under power the drive just makes a zing noise about every five seconds or so. I don't know how the freeze method would do any good and the re-drop method hasn't panned out either. The heads are parked but should I worry about any further damage jacking with it?
