If you have a CDROM drive and a Hard Drive on the same cable, and this cable is plugged into a controller that can handle UDMA66, it will revert back to 33, because that is what the CDROM can handle. If this is the case then seperate the two, plug the Hard Drive into the first controller and the CDROM into the second.
