Did you hook the HDD as a UDMA33 drive or as a UDMA66 drive?   When you
hook up your UDMA66 drive to a regular old IDE riser on the MoBo it acts
like a UDMA33 drive.

# hdparm -t /dev/hde

/dev/hde:
 Timing buffered disk reads:  64 MB in  3.30 seconds = 19.39 MB/sec

# hdparm -T /dev/hde

/dev/hde:
 Timing buffer-cache reads:   128 MB in  1.98 seconds = 64.65 MB/sec
