Ok, so I was trying to transfer my data from the old fat hard drive to the slim hard drive. I plugged it in and I got nothing after a few seconds, so I tried to do it manually by going into storage and configure it. I get this message that my fat hard drive is below recomendations and worse, I can't even access all the data stored in there. And when I tried to put my hard drive back on my old 360, it wouldn't even detect the hard drive or the contents it has. I have years worth of info in there and I don't want to lose it. Can someone please help? I really don't want to start from scratch on all the games I've played.
