A relatative has a Dell 5150. He's added a second hard disk to it. The problem is the the disk isn't being picked up. Is there a jumper setting or BIOS setting somethere that tells the system that there is a second disk? The layout at the back of the motherboard is something like this. There are 4 L shaped keyed connectors that connect to the SATA drives.
If I swap the new disk cable with the CD, it picks up the disk. It looks like the second set of connectors is disabled. Any idea what should be done to enable them?
Code:
===== USB ribbon
L <- original disk blue cable
L <- CD orange cable
L <- new disk cable
L <- empty
: | <- yellow jumper
