I purchased a 2TB Seagate Barracuda this week for internal mass storage in a new build and Disk Manager will not detect it in order for me to format it for use. The weird thing is, device manager does seem to detect the drive. I tried to disable and renable it. I've also tried the unplug>restart pc>shutdown>plugin process but it didn't help either. The drive also could be found in the bios. I've even tried formatting the drive on my personal rig and even there I ran into the same issue. The rig I'm working with has a GA-Z170x Gaming 3 motherboard by Gigabyte with a Core i5-6600K. I added a screenshot for additional visual aid. Any insight on the issue is greatly appreciated. If it's a drive issue, I will return it since it's still under the return policy.
