I wouldn't expect so.  Supposedly any controller ATA-3 and above can 
use the 80 pin cable, but don't hold me to it.

Well, I just bought a 100 pack of 16X DVD's, so I reckon I'll be 
picking up a cable to make it worth the extra money I spent on the 
disks.  Thanks for the info.

Thanks,

Kevin

In the ATA/ATAPI-4 standard that introduced the Ultra DMA transfer mode 
set, a new cable was introduced to replace the old standby: the 
80-conductor IDE/ATA cable. The name is important: the new cable has 80 
conductors (wires)--it does not have 80 pins on each connector, though, 
just 40. This means that the new cable is pin-compatible with the old 
drive. No change has been made to the IDE/ATA connectors, aside from 
the color-coding issue (see below).

The obvious question, of course, is this: what's the point of adding 40 
extra wires to a cable if they aren't connected to anything? :^) Well 
for starters, the 40 wires are connected to something, just not their 
own pins on the interface connectors. The extra 40 wires don't carry 
new information, they are just used to separate the "real" 40 signal 
wires, to reduce interference and other signaling problems associated 
with higher-speed transfers. So the 40 extra conductors are connected 
to ground, interspersed between the original 40 conductors of the old 
cable. Any stray signals that would "cross-talk" between adjacent wires 
on the 40-conductor cable are "absorbed" by these extra ground wires, 
improving signal integrity. The extra ground wires can be either all of 
the even-numbered wires, or all of the odd-numbered wires in the cable.
