Yup, that's the culprit!
Check to make sure the ribbon cable is in there securely, it caused a
similar problem on my system.
The other thing to try is a tuning command like:
hdparm -c1 -m16 -a128 /dev/hda (or whatever drive)
then retrying the 'hdparm -tT /dev/<whatever>' to see if it made an
improvement.
