Linux and OpenBSD-2.7 both use the ATA-66 capability without errors and generally show a 25%-30% increase in performance over ATA-33 measured with Bonnie. So it isn't double the speed, it's still a marked improvement. The suggestion I received regarding replacement of the 80-wire cable with a 40-wire cable is specious and non-responsive. Apparently no one in a position to be able to properly evaluate this problem cares enough even to post.
