Just make sure you take an image of that drive so if you screw up your 
have an out. Additionally, there are data recovery companies that will 
recover your data. Since the hardware is working, it should be less 
expensive. If you decide to go this route, make sure you check their 
reputation. A couple of years ago when one of my HDs died and I was 
unaware that my backup was corrupted (32-bit system with a virtual 
machine that screwed it up), I sent the drive to a company in Chicago 
since the only local companies with good reputations locally were too 
expensive.
