Alright I pulled a Western Digital Sata 500GB hard drive out of my Dish DVR and when I put it in my comp it doesn't show in the bios,disk management, device manager. But in the bios where it is plugged in the port that spot is it is blank. Doesnt show the name of the disk or nothing just blank. Whats up? It was working when it was in my DVR before I pulled it.
