You're oversimplifying the conditions of what must be done in combination. If you jumper your drives as master and slave, it doesn't matter where they're plugged in. The cable will be ignored by all but broken hard drives. If you jumper them both as cable select, the cable determines which is which (master on the end, normally). It is highly inadvisable to jumper one drive as master or slave and the other as cable select, and that's the only time you're going to have to worry about what position on the cable the master or slave jumpered drive is placed. There is about only thing you do have to do with an 80-wire cable, and that's plug the motherboard end in at the motherboard. It's only at that end that the interspersed ground wires (the extra 40 ones) are grounded. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
