Forum:Xbox - Lost my character file

I recently lost a character I had leveled up to 41, it just vanished. I currently live in a dorm and my roommate also has an xbox. I have been needing to transfer my character from xbox to xbox because I have been letting someone who does not have an xbox use mine. So since I was being nice and letting them use mine I would transfer my save file from my xbox to the memory card and then proceed to save it on to the other memory card. I realize this is probably not the smartest thing, and the reason I didn't just keep it on the memory card is because I would borrow the memory card from a friend to specifically move my save file. Anyways, today I was going to move my save file back to MY xbox from the memory. I did my normal thing by loading border lands up with the memory card as the primary save device, loaded my character and went into the game. Once in the game I would change the storage device to the xbox hard drive and then save the game and exit. Later today when I tried to play I tried to load up my level 41 and it was not on my harddrive. I checked the memory card and it wasn't there either, nor was it on the other xbox I had been using. It just vanished. I didn't delete it from any of the systems.

I have started a brand new character because I really enjoy the hunter but I would rather not level him all the way back up to where I was.

Does anyone have any ideas?
