I have completely rebuilt my system. Bios recognizes both the hard drive and cd drive. The hard drive is set to primary master. The cd is set to secondary master. It has no slave drives. When I run the diagnostics tool that came on the the cd with the hard disk, it does not detect the hard drive. I tried to use the windows cd to partition the disk but that hangs up also. It seems to me that the cd drive and hard drive are not communicating. Please help!!!!!!
