answer:What OS and/or burner software are you using? If it’s Windows, my guess would be a bug in Windows and/or the drivers for your burner, where it can get into a state where it gives you bogus information about the drive state, and hides the actual error condition from you. In that case, I’d try putting in a different blank CDR (it might be it doesn’t like that particular disk, and the bug is it doesn’t tell you that), and if that fails, I’d try restarting Windows and trying again, also starting with a different blank CDR.
