So your barking up the wrong tree. I friend of mine went through a devoice a few years back. He did not get his personal xp pc in the settlement, only the hard drive which makes a squealing noise when running. He tried to install it into his dell desktop. But not being a computer geek he know nothing about master/slave on the ribbon or the jumpers on the H.D. Have no idea what damage he may have caused doing this. He told me it was dead and he wanted his data recovered. I used a ata to usb adapter and connected it my win10 lap top and was surprised when it spin right up and indeed it was noisy. Win 10 automatically ran disk scan on it and fixed the damaged index. I had to muck around a bit to copy off 12gb which was everything but 2 router manuals in pdf format. In my book that is a successfully data recovery. Never needed to use freebsd to recover data. The lesson here is try the simple recover stuff first, especially if it's a Microsoft drive. Thanks to Polytropon from Magdeburg, Germany for his post listing the freebsd tools for data recovery.
