well it looks like my HD is a goner! my xbox was modded when i got it. i do not know what chip was used to mod it, but it is red and has a switch wired to it. im pretty sure it was running evo x, but im not 100% sure. after being dropped i was getting a 07 error, and now i get 09 error and the HD is making a weird noise. i need to install a new HD, but dont exactly know how to setup the new HD to work on my xbox. any tut, or thread that can explain how this works.
