CD-CRW time outputs errors

I would like to know if anyone out there can answer the question of why and how can I prevent from constantly making coasters out of good CD’s everytime I try to make a backup copy of my CD’s. The burner works fine when I copy from my harddrive, butI continually timeout when I copy CDtoCD? Hope you guy’s and gal’s can help. I’m at grizzly55m@hotmail.com
