is this an external drive if so take it out of the case pop it into a machine then see if you can get files off of it? also if it comes down to it you can preform a quick format and recover MOST of the information off of it. also taking the platters out isnt the best idea the read/write heads hover about 1/16th the thickness of a peace of paper from the plates themselves even the slightest peace of dust could set it off track.
