Clone CD... my writer doesn't work!

[(none)]

Everytime i try to make a backup of a game(e.g NHL 2001, NBA Live 2000 etc.), after 3-5 seconds, it goes into a mode where it does the same thing when vertifying the disc when you start it up. And it just stays in that screen until i can't take it anymore (After 30 minutes). Now my writer (Acer 6x4x32) can't read Subchannel data or CD Text... Is this relevent? Or am i waiting too short?
