I just installed a brand new Western Digital Hard Drive 160 gig. I partitioned it with FDISK, then formated, then did a clean install of windows XP. Everything was fine until after i finished the installation, and i tried to connect my old maxtor 20 gig so i could transfer some files over, and the computer stopped reading both hard drives. When i start it up, the computer can't boot from either drive. I've tried disconnecting each of the drives and only booting with one connected, with no luck. I also tried changing the gray strip, I can't remember what its official name is, but that didnt help either. When I go into BIOS and let it auto detect my drives, It wont recognize either of the drives.
