I'm new to the PC game. I built a rig with an SSD. And remembered I had an old HDD sitting in my closet. Plugged it in and immediately saw it in device manager a few weeks ago. Went to install a game today and it told me I'm almost out of storage space. No way I used a TB and a half. Sure enough the drive won't show up in disc manager or my cmd/discpart either. It shows up in device manager and in bios. What am I doing wrong? I've also tried switching cords back and forth between the sad and the hdd? Do the cords need to be "flowing" a certain direction?
