I have a WD Green 2tb, but it was full because I've tons of games and short film projects. I've decided to expand the HDD by buying a WD Black 6 tb. I've followed every steps from a video to migrate the HDD but some I ended up messing up the HDD because it's only 2 tb usable now. I'm sitting here hopelessly frustrated because I tried everything what I could do to recover it back to 5.5 tb. I've tried formatting it, but with no luck.
