Hey, I would be careful about swapping controller boards. It's been a few years since I spent any time working against bare metal drives but the controller used to have sector remapping info stored on eeprom. If that info has moved to the platters then you should be good, otherwise you may find some weird errors as the two drives are *very* unlikely to have the same set of bad sectors mapped the same way (the same sectors would have to fail in the same order).
If you can find a way of copying just the eeprom sector remapping data from the failed controller to the good one, then you may be OK. If this is a case of better some data than nothing then you may as well go ahead and try. This sounds a lot like the bullet I dodged about a year ago. I'm still very annoyed with Seagate because it cost me close to $400.00. That problem manifested when a failure occurred after exactly 'n' power cycles. My, admittedly brute force, solution was to buy a 2nd NAS and copy all the info off the old NAS (with Seagate drives) onto the new one (with Samsung drives). I consider myself lucky - everything was on UPS so I didn't risk triggering on power cycles. Slow & expensive but low risk. I think it's time for your friend to spend a few minutes thinking about the value of the data. If it's worth it, send it to a recovery op - look for special pricing because Seagate did a deal last year with one outfit and recovery was flat-rate US$75.00 for my problem. If the data is just nice to have then he can try the recovery himself as a hobby. Or he can ask around for someone to help him - might cost him a bottle of Scotch though.
