- Increasing UDMA mode on older laptop

memory and a 5400 Hitachi(8 meg buffer) drive capable of UDMA 5. However when
when I look at the DMA values with PC Wizard, UDMA mode enable is 2, while the
drive shows it could run at 5. A bit of research indicates the cable connection
from the hard drive to the controller needs to be changed from 40 to the newer
80 conductor versions to get beyond UDMA 2.
A. Is such a cable available for a older laptop? (I'm comfortable opening the
machine, changing things and I have the hardware manual for the machine)
B. If I did manage to change the cable would I need to upgrade the drivers and
would it actually get me to UDMA 4 or 5?
