You probably void your waranty on both drives if you swap the control 
board, it may require special tools you don't have, and I have done it 
in the past. Can you get to the point where it fails and cool it with a 
shot of freon (or whatever is politically correct these days)? May be 
thermal, in which case you run it until you back it up, then waranty it.
