I have a WDC 3TB Hard drive in my Computer along with a 120GB SSD in it as well. It is custom built from scratch, this may or may not be the reason since it is my first build. My computer recognizes that both drives are working in the computer, it the BIOS and in Device Management, but in Disk Manager only my SSD shows up, I want to get my Hard drive to appear so I can store stuff on it because my SSD is just about full. I've looked and researched a lot and I cant find a solution anywhere, please help!
