HELP! I can't burn a cd!

I got a Philips Pcrw5224 cd - burner. When I try to burn a cd I get
messages like “calibration area full” or “kon end-track niet
uitvoeren”(something like: Wasn’t able to proceed end-track)
This happens when I’m at approx, 6 % of the burning.

Does anybody know what’s wrong and what I should do about it?

Which Nero version are you using? Upgrade to the latest version and if applicable upgrade the firmware of your drive to the latest version.
