So, my Sansa has an IED burn, in other words, the screen does not display anything. Furthermore, when I tried to hook it up to my xbox 360, I formatted it and had it have xbox memory. Is there anyway to format it back to what it was?

I don’t know why you formatted it in your xbox, but you should be able to format it again with your computer. But that’s not going to solve your screen problem. Format or not, if you can’t see anything on the screen you cannot navigate on the player.
