I don't know about IDE, but I'm pretty sure that's a big no-no for SCSI
cables.  The alternating conductors in the ribbon cable are sig, gnd, sig,
gnd, sig, etc.  And it's electrically important (for proper impedance and
noise and cross-talk rejection) that they stay that way.

I think the same is probably true for the schmancy UDMA66 cables too...
