@Alex: could you tell us the exact exact steps you took to install it? Like everything, every option, what you did, how you installed. Could it be that it doesn't like 500GB disks? :) I've installed on 80GB, 750GB, with RAID1, and found nothing. I have an 500GB WD too, and I can try that, but I don't have any fancy controller (I think). SATA is set to AHCI (as opposed to IDE) in the BIOS though, not sure if that matters.
