Hard to say with that. Bringing it back to life as in getting data?
Or has in it being just fine again? I usually work with dead and damaged drives and recovery is much easier then repair. You could just let it rest or just cycle it on and off a few times and yes it may just decide to work for you. You could go a head an see if you can access it in dos and have it low level format, which will really shake things up. I have seen um tapped, banged, shaken and frozen, but any impack, particularly while spinning usually can cause some particle damage. You can swap controller cards with an exact model, you can even open it uo and look around, but a clean room is best for this, but 50% of the time you may notice no differenve(damage) during reassembly being very particle aware in a non-clean environment. I guess the answer I would give is that its pretty much an unknown.
