I've had the same Hard Drive since I bought one of the original Xbox's and now its startingto give me trouble. I recently had to wipe all the content. But thats not the problem right now, I was playing AC Brotherhood last night and it said the memory device storing this profile has been removed, but I didn't get signed out so obviously no one took the hard drive out. I ignored and went to play this morning and my profile just magically wasn't on the hard drive, so I tried to recover it. And it said there was a problem performing this action. No error code, just a problem. I tried moving my profile from a memory unit to the hard drive and the same message appeared. But I could move my brother's profile onto the hard drive. Anyone know the problem? I'd like to go more than a month at a time without deleting all my content (as I did about 3 weeks ago).
