Can't be that I'm afraid. The disk is detected as the wrong size by
windows, linux and the machines BIOS. Have tried two different sized
disks now (320GB and 500GB) and the reported size (and free size) was
exactly the same in both cases. Also, I haven't checked but as far as
I'm aware 4k sectors only tend to be used on disks >750GB which neither
of these disks are. Imaging software is the venerable GNU ddrescue, I
might try again with standard dd just for good measure if I can't turn
up any better options but I've done this procedure many many times and
have never had a problem with gddrescue before :/
