combat flight simulator 2?

does anyone know the protection on cfs2, disc 1 is safedisc1 but on disc 2, copy detect says none or unknown although there is protection as cdrw picked up error reading blocks(unreadable errors) tried using clone cd using safedisc paramaters ,disc 1 no problem but disc 2,wouldnt work, any ideas?Brad

TO COPY CFS2 I USED ADAPTEC EASY CD CREATER 4. CREATE AN IMAGE FILE OF ORIGINAL, THEN BURN IMAGE FILE TO BLANK CD.
