You should be using an 80 conductor IDE cable which means CS is the right jumper. Master is determined by what connector you plug it into.

I am using AMD K6 2/400 CPU P5 SS-ME mainboard, recently I bought a new 40 G harddisk try to replace with the defeat one ( which is only 6 G ) and it couldn't detact even if I put the jumper on Master or Slave, and it can be detacted only when I put the jumper in CS ( cable select ) , and the motherboard can only reconized it in " Slave " mode, The data cable was correct, jumper was correct, is it because it cannot detect more than 40 G since it was only AMD K6 ?
Is there anything I can do ?
