I had a Benq who worked fine for some time and then it wouldnt burn faster than 16x and now i'm down on 4-6x , when i tried to burn faster it would result in burn failure and buffer underrun.

I updatet the firmware and tried to clean the air vents and a new Nero version still the same problem.
Okay its wrong with the CD writer i thought so i got a used Samsung 48x max that for sure works in 32x (my da' used it in his computer).

This burner had buffer underrun protection so the burn process went to completion and Nero said burn process completed sucessfully, and that buffer underrun was avoid like 115 times.
When i put the cd back in and tried to open it it was nothing on it and it said the cd was unformatted.


So the problem is what do i do with my computer that destroys all my cds with the buffer underrun.

I've tried defragging the hd. Didnt work.

I would check to make sure DMA is enabled.
Also I would try burning without any other programs running in the background (SETI@home, anti-virus, web browser, ect)

Yes, it sounds like DMA is disabled. You can find instructions on how to enable DMA in the FAQ forum here at CDRLabs.

Where do i enable DMA? And i shouldnt be have to shutdown every program i use when I'm about to burn. Thinking about USB 2.0 burners. Comment?

No, you shouldn't have to shut down all of your programs when you burn, but David mentioned it because it would be a good thing to try in the process of troubleshooting your problem.

You took the words right out of my fingers.

Thanks I'll check it out right now and see if it works.
