Oddly enough, I've never known that there was such a beast as a "cable- select cable" or a "non-cable-select cable" even though I've built at least 200 systems. I've just always jumpered drives as master/slave as required.
How would one detect which type of cable it is?
One of my UDMA cables has 2 different colored connectors (blue & black?) and can be used with Cable-Select....
I only discovered that quite recently. I think it' part of the spec from ATA-3 which basically means all contemporary kit.
Dunno about those 40-pin cables you still see at Tricky Dick and Tandy and such.
40 CORE (they both use 40 pin btw) cable - doesn't matter which is master slave or even motherboard connector.
80 CORE cable can cause havoc if you do not stick to the order: BLUE - MOTHERBOARD BLACK - MASTER GREY - SLAVE
Any other combination can cause real problems, or minor ones depending on motherboard. I've never seen an incorrectly wired IDE cable run at ATA-5 speed properly.
