Swap em and make sure that if they are IDE, one is set for master and
one for slave.


There are cables that support cable select (these have one blue,
one grey, and one black connector), and cables that don't.


...with a
modern, ultraATA, CS supporting cable.
When swapping cables around, the blue connector MUST be to the
logic board; the grey is for the slave, and black is the master.



The end connector is the slave, and pin 28 is not connected on the
slave connector for a CS compatible cable. So just cut #28 (counting
from the coloured side) and you have a CS cable.



Clearly, you're referring to 40-wire cables (UltraATA are 80wire
cables with 40-wire sockets). Those 40-wire cables are IDE; the
recent cables are all UltraATA, and are color-coded.

For UltraATA, the end connector must be the master (it's in the standard).
Regardless of the CS feature, UltraATA must be terminated at the
ends for signal-propogation integrity, and that means a
sole unit (master) on the bus must be on the end connector.
