When I got a 500 GB hard drive to replace my 160, the only thing that worked was putting all my save data on a flash drive/online storage, and downloading ALL the games, updates, and all that stuff all over again. As long as you still have your save data, it isn't too big of a burden.
Been away for a bit, but sneaking back in.
Gaming on: PS4, PC, 3DS. Got a Switch! Mainly to play Smash
