IM GOING TO BUY A NEW HARDRIVE 2MARROW IT IS A WESTERN DIGETAL 80 gB HARDRIVE 7200 RPM 8MB bUFFER i have a softmodded v1.0 xbox the model number is WD800JBRTLW
yeh i had the exact same but to be sure look on other xbox threads one of them is the list which hdd works with which version
take it back its obviously not compatible with it unless u no someone with a differeent ver xbox and its softmodded then try on that
