I have been told that the hpt366 driver attempts to probe for an
80-wire cable and fails, falling back to UDMA2. Obviously, this cable
probe is nonsensical with SATA, and removing it from the driver fixed
things. This happened to a friend using Maxtor disks. I have not had
the same problem with my Seagate disks.
