You have to either swap the entire drive, or get a matching logic board. You can get by without any drive attached, with just your logic board plugged in, once it's working 100% and paired.
If you have another drive, try attach the entire thing, with it's own logic board (not the one you're using now). You will have to re-marry them but it should be fine then as the logicboard you're using now sounds dead.
Oh yeh, this is entirely down to your BR drive.. Thank Sony for the hassle!
