So I have a hard drive that is specifically for my ps4 but something happened and now when I turn on my ps4 my hard drive is not getting detected. I tried to get another cable to see if it was the cable but it wasn't. Now I am trying to figure out a free way to reformat my hard drive to see if it will work again with my ps4. I have about 10 or so games on it already and its a seagate 2 tb hard drive. Any suggestions would be very helpful.
