I fixed PCs for about 20 years. Most companies consider the controller board and Hard drive to be an indivisible unit; if you have a warranty, you'll void it by removing the screws.

That being said, you can either -

1. Send it out to a drive recovery place, haven't done that in about a decade; so I'm sure it's not a $1,000/gig any more, but I bet it hasn't come down much.

2. Actually try replacing the board. You'd have to do a lot of digging to find the actual board; but it's mainly the cable between the board and drive that's the problem. As mentioned previously, most places sell the drive and board as a unit.

I don't know what the connection looks like, so if it's a Zif (zero insertion force) connector, you may just have to carefully undo the lock. 

If they have it glued or soldered on, it might be time to see the pros. You might be able to find the drive used; drive capacities and technologies change so fast, it's not easy to find old drives after a couple of years. There's probably a geek place out there that can help you out; maybe even a service that could repair or replace the board.

Good luck, hope they get you up and running.
