Oh bugger it, I should have asked Google in the first place :-) Mind you, it
took a little looking (4th page of results for "ATA66 cable description")
but I eventually found this on Western Digital's site
http://www.wdc.com/products/drives/drivers-ed/ata66tp.html where it says
that an ATA66 cable has 40 connectors at each end, but an 80 conductor
cable, interleaving an extra ground line between every pair of existing
lines, which is of course a big crosstalk win. Presumably these ground lines
are connected to ground inside the connectors somehow. I did also read on
another site that one end of an ATA66 cable is bright blue and that it is
essential that this end is plugged into the controller/motherboard and NOT
the drive.
So that's it - I hope you're all happy - I know I am - now I just have to
buy a couple of the new Maxtor 15GB per platter drives (available with up to
4 platters) and have a play.

Niall
