Probably a stupid question, but I recently bought a 4TB hard drive to replace my filled 2TB drive in my machine (not the boot drive, one of my 3 data drives). I've been using a 4TB drive in an external enclosure for some time as a backup drive, and the new drive arrived the other day. To transfer the data from the drive it's replacing, I installed the new drive in my external enclosure, formatted it (as GPT), successfully saw all 4TB available, and copied the 1.8TB of data from the old drive to the new.
All that went fine, but when I swapped the drives internally, Windows 8.1 only sees the drive as a 2TB drive, with the rest unallocated, and it won't assign a volume to it (so I can't actually interact with the data at all). I'm assuming there's a BIOS setting or something along those lines to work correctly, but I'm not sure what it is. Also, Windows in the Computer Management section is saying that it's an MBR disk, when I definitely formatted it as GPT, and the full size of the disk was available when it's used in an external enclosure. The machine is the one in my sig. Help?
