Is there a way to test a CD burner to make sure that it is making quality burns? The reason I'm asking is because my Sony CD-RW burner is having trouble recognizing certain CDRs and I'm starting to notice random C2 errors on recently burned CDRs where I never had problems before. The C2 errors are in different places every time I test them, which leads me to believe that it's the drive and not the CDRs. Then, sometimes when I run the test again, there are no C2 errors at all! I'm running Nero 126.96.36.199 with Windows XP and I use Nero CDSpeed to check my CDR quality. I want to make sure that my burner is still performing up to spec because I don't want to burn anymore important CDs if it's time to buy a new burner.
