Hello my friend would like to switch out a hard drive from his non working original xbox to a working original xbox, there are no differences in the type of xbox, they both look like this http://www.technobuffalo.com/wp-content/uploads/2013/07/Xbox-console.jpg . What I am wondering is how I would do this. (I know how to take it out just didnt know if there was anything extra that I would have to do).
