Ahh, I did not know that. Does this apply to master/slave connections on the same PATA cable as well? I know zero about PATA, but I assumed from the terminology that master and slave needed to cooperate rather closely.
And for newer systems well the motherboard tends to be festooned with random SATA controllers, all separate!
And how. You can't swing a dead cat without hitting a half-dozen ATA ports these days. And most of them are those infuriatingly insecure SATA connectors that pop off when you look at them cross-eyed... --Adam
