Help please!! I've been trying to install a second hard drive to my PC and can't get the thing working. I follow the instructions and connect to the slave connector on the ribbon cable and the correct power source. I have set the jumper settings to slave configuration (for 16 heads, but I have also tried other configurations with no luck) so that my original hard drive continues to act as master. When I turn on the PC, when it is booting up it tells me that it is searching for IDE drives. It refuses to detect the master now, then comes up with the message, "Secondary slave hard drive failure" (the DVD and CD ROM drives being the two primary drices, master and slave). I'm very stuck as to what I'm doing wrong and would be grateful of any advice….thanks very much!
