My samsung hard drive model hd103uj with sata was already set as 2nd hard drive as a backup drive in my old computer. the 1st hard drive was eide and it was set as master. I replaced my old motherboard with asus P7H55-M PRO. I want to keep my samsung hard drive as back up. So I bought Seagate Barracuda drive with sata as Local Hard Drive C for windows 7. It works fine, then I installed the samsung hard drive, it does not show up in "My computer" but it does show up in "Device Manager" and it says it is working. How do I fix this?
