I just opened my CPU and saw that there are 2 seagate hard drives installed. One hard drive shows up and the other one does not. Both are connected to the power and SATA and both hard drives have 500 gigs space. Under Device Manager when I expand Disk Drives I can see 2 hard drives listed with same serial numbers.

When I open Disk Management it doesn't shows any other HD that is unallocated or not initialized yet. List volume doesnt shows it either. Please advise.
