I've always assumed the problem was with the with the motherboard, as the DVD will always successfully boot a windows installer, so I assumed everything with the drive was OK. On further inspection, it appears that the drive falls down when being accessed from the WinPE environment, much the same as in linux. I've tested this on another PC and the result looks to be the same. I'm going to do some more testing, and will send another email if I find out otherwise. But I think we can consider this closed. Sorry to be a bother.
