Re: Percussive maintenance
Done the same with a 3 1/2" drive - around 250GB IIRC.
Also had one that only worked when cold, so being in the depths of winter had it hanging out of the window by its IDE cable to get the data off it.
Others with sticky bearings required a percussive start (seagate barracudas of a certain vintage)
Can't do any of that with SSDs though :-(
