backing up my game cds??????

[lollyruk]

i noticed on the game index that the best way to back up your games to get past protection or something is to use nero i have a new cd writer and when i tried to copy one of my games for backup becuse it was badly scratched i followed the instructions on how to make the cd but it says use 1x speed this is a problem cause my cdrw is new and wont let me copy at this speed so when i put it on 8x speed it did the cd ok but when i tried to use it my computer wouldnt read the cd what have i done wrong?

i have prassi primo cd software if anyone knows how to do the same only using this software could you let me know cause im really confussed..........................
