my friend did the same thing with his hard drive.. When his xbox got the ring of death he said that his hard drive was on it still and then just asked if they could send it back.. and they obv cant so they sent him a new one and gave him microsoft points for all of his other games.. and he also called xbox and said that he bought a wireless mic and it wasnt working like a week later.. but walmart wouldnt take it back and they sent him a new one..
