Well, the cable is just one part of the game. You also need a controller
that's capable of the higher DMA modes. Your laptop for sure only has a
controller capable of UDMA/33, so a 80pin cable would not help You anything
at all...

Oops forgot about that part of the equation and there's no way I can change the
controller. Guess I live with UDMA/33 for now.

Thank you for the quick response.
