Hey Im might get a 500gb harddrive for my xbox I was wondering if there is music or whatever allready on there and I use hdm and copy the c and e to the harddrive will it overwrite all the stuff or be additional and If the locking is unsucessful what will happen If I plug it into the computer with all the stuff in it will it still be there or will I need to format and lose all the stuff thanks for the help.
