your thinking of something else thats for putting a new hd in your xbox. you can use the hd swap with a locked hd. couse the xbox powers on and unlockes it. youpush paise/brake befor you pc sees any drives power on the xbox wait for the dash to load. wile the xbox and pc is one still paused you sawp the ide cable from the xbox mobo to your mobo. i sugest unplugging your pc hd first. so with the xbox on and its ide cable pluged in your pc resume booting using the xlinux cd you have acess to your xbox hd.
i put the new files on the xlinux iso so all i need to do is to rename those font files with xlinux for backup and cp the new stuff over using there guide. youdont ned to use gogo couse your not doing the 007 expolite or that command does it all for you. og yea when your done plug the ide cable back into the xbox and power it down to make shure knothing gets cruppted. and of course reassemble your pc. but rember ide isnt hotswap compatble and thers a slight chance you could fry yout pc or xbox but noone has had this happon to them as of yet.
