Why is it connected to the secondary slave? It's also only achieving
UDMA33. Unless it's an old laptop, that should be at least 66 or 100.
Did you move the drive and change the cable?
I would have guessed that putting it there behind your DVD would be
enough to cause a couple of problems in itself. Although order and
such doesn't matter too much, that will cause a slow down.
