I was just curious as to if there's an easy way to find compatible boards for hard drives so I can refurbish some. I know that if I swipe a board from the exact same model hard drive as the one I'm replacing the board on, I'll be good to go, but I was wondering if as long as I have the proper specs for the hard drive, would the connection from the board to the rest of the drive be the same, and if so, would it work if I swapped one with similar specs?
Yes it is possible as you suggest. but the replacement boards are expensive, often more expensive than buying a new hard drive of simmular size / spec. Its only really done if you need the data from the dead drive.
