I just bought a new PC to use as a plex server. It only came with a 1TB HDD so i swapped it out with a new 4TB hdd. Fresh install of windows 10 later and im only seeing 2TB available. I have seen i need to convert the disk to GPT (its listed as NTFS now in disk management) but i can not use any of the unallocated space or format it. The PC only has one SATA port so I cant use another drive for the OS install....any suggestions? Thanks!
