Try the Harddrive as the only drive in the system on IDE 2 . Won’t matter if the jumper is set to slave or master by itself. If no luck, then proceed to the next step. If it works then the problem is the jumper settings on your drives. Also make sure the RED Stripe on the cable is facing the RIGHT side of ALL the drives when looking from the [B]back[/B].
Double check that the secondary IDE Channel has not been somehow de-activated in your bios by hitting DELETE as your system powers up. Navigate to INTERGRATED PERIPHERALS in Bios, and check that your ATA IDE CONTROLLER is set to “BOTH”.
Good Luck and Welcome to the forum
