without any further info I am assuming that you DO have the embedded ROC (raid on chip) controller..to confirm this look on your system board...locate the scsi connectors...to the right of the second one there is a small white socket that should have the controller in it..it will look something like a laptop memory dimm with transistors on it..if it is there then confirm that your drive cable is attached to slot 2 .thats the scsi connector closest to this chip..when that chip is in port 2 becomes the default array channel and port 1 stays open for standard scsi...
