*No replies hey?
Well I think I figgured it out!
Thanks to a fellow xbox modder, I read a post on installing a switch to change between 2 xbox hds.
So all I needed to know was to switch between hds, install a switch on wire No.23 on the IDE ribbon between all hds. Switch power on and off between switches and rice and pea, there you go a 6 HD switchable incar MP3 system.(for pennyless hobos like myself)
*Just a hello would have been nice
