Ta. Did all the above last night (eBay's I Want It Now is pretty much hit and miss). Seagate official forums are full of proprietary bum-kissers who won't help anyone wanting to swap boards out coz big bad Seagate say it's naughty. But found
loads of others (including
http://www.deadharddrive.com) which pointed to lots of occasions where people had successfully done the board swap on Barracudas. Looks like a common problem. Hardest thing was trying to find a drive/board with the right firmware, but googling it found a UK company with one in stock, and as I say, this drive is on it's way now. Hope it saves me a few bob..
