I have a Philips 800 Series CD-RW that receives a power calibration or buffer underrun error every time I try to burn a CD. The odd thing is, this just started happening on about the last 10 CD's I have attempted to burn. I have tried different types of media, to no avail. I have also tried to run the CD laser lens cleaner, and the burner fails to even recognize this. So, I'm kind of stuck at this point. Any suggestions?

Try this post and see if it help if not please let me know and I'll see what I can do.

I have had the same problem, and tryed everything, incl. new medias, new drivers without any success.

After measuring the +12V power to the DVD unit in the PC, I realised that this voltage was changing from +11,4 to 12,8V, which is unacceptable during power calibration.

I have inserted a DC to DC converter in the 12V supply to the DVD unit. This DC converter creates a stable 12 volt with a 7 to 18 V input.

After this everything works fine.
