Have you tried putting a different CD-R into the drive? Perhaps you have a few bad ones, or they have already been written to and closed?
Sorry but difficult to properly diagnose without knowing more surrounding the conditions of what is going on....is it a new computer, what are you attempting to copy over, is it a new cd you are using, are you sure it is a writable CD or DVD that you are using....what software are you using for the writing, and are you attempting to copy copyrighted material over?
Sorry just a few of the things I would look into off the top of my head
It looks to me like there's an issue with the CD you're using. Sometimes random errors happen during the writing process (especially if you're using anything moderately RAM-intensive) and the CD will be ruined. If you keep trying to write to that same CD the writing will fail every time.
