I came here hoping to find an answer to this...suddenly my hard drive in my slim started making my xbox slow down big time on every action I tried to do including start up. Here is the kicker....Microsoft will give me a new hard drive but only after I send the old one in. I can still retrieve the files on the old one but yeah...no such thing as a memory card over 32g that I've seen. lol How the hell am I going to stow these files until they send the new one? Ugh!
