This is all of the current knoledge I know on this subject. ixtreme for the samsung drives is ok to play on live but is it ok with backups or originals or both? hitachi's cannot play due to the media detection. By the way what is media detection. anyways if you get caught by microsoft then you can never connect to xbox live ever again unless you purchase a new system. yup thats all I know so how about we fill it in for everybody like what you can and can't do on live. Such as play backup games or just originals. I have an Hitachi drive dj59 so if you have any info on the stealth firmware 2_4 that would also help me out thanks again.
