Please help with my Hard Drive problem.

My computer will not recognize my maxtor slave hard disk. It is not listed under disk management either. It is enabled in my bios. When I try to detect it in my device manager it says its not properly connected to my computer- “code 45”. Well, I’ve reconnected all my wires 5 times at least, my jumpers are set to slave. My os is windows xp pro. Please help.
