And someone else quoted the last two in reverse. Can someone PLEASE go get one of these friggin cables and settle the argument? Good color vision required of course :)

Gene:
I went through some Maxtor data sheets, and they say that blue goes to the motherboard, gray to the slave and black to the master. I noted that Maxtor refers to the cable as a "UDMA interface cable". My understanding is that the 80 wire cables came into existence to handle the higher data speeds required by the UDMA interface, and don't have anything to do with cable select. Maxtor also states that the supplied cable is to be used with either type of jumpering. Although Maxtor does not explictly state that the gray/slave black/master must observed when using master/slave jumpering, one of my hardware references [1] does say so.

It's left as an exercise for the reader to dissect a cable and settle the crossover/straight-through/termination questions. My eyes are too old for that kind of crap -- especially at this hour.
