I bought this hard drive a while ago it has 1tb on it i bought it because i ran out of room on my old one. It worked fine until one day I tried to download a game on steam and it said disk write error. I tried to play a game with that hard drive and it worked, but if there was an update for the game I could not play it. I cannot create a new folder in the hard drive but I can access the files. I can moves files from the new hard drive to my old one. I am utterly confused.
