I just plugged in another Hard drive to my PC... yes I set it as a slave and the main one as master and all that jazz. When I Turned my comp on I got all the windows is installing your hardware meassages but I went into My computer and its not there. Only the Master is there. I found it in the Bios at start up and it is set as master and I found it in device manager and it is "working properly". I also tried adding new hardware and i just got the message at the end saying your horware is working correctly.... Any Ideas people?
