hmm sounds like he didnt mean to use that hdd on the xbox and tried to experiment and went horribly wrong so he wanted to put it back before whoever he took it from doesnt find out or he just messed up big time, i like the first theory.. also when do i turn to a senior member ive nearly done 500 posts or more cant remember @edit i thought i did over 500 nearly 300 hmm
Will your computer read the drive or did the xbox lock it? if its locked you need to find a way to unlock it (theres many guides out there) if it can read it then just find a program that will sweep the whole drive clean. Use a program like hd cleaner. google it.
