Hey! Title says the gist of it, just got my computer running today and it's only showing my drive from an old PC correctly, and that's almost full. I installed another hard drive, a 2TB one, and it shows up in the BIOS fine. Under Disk Management though, it only appears to be at 931.51GB. I'm using a Asus - Prime X470-Pro Motherboard. Really looking to test this thing out, thanks.
