Interesting conclusion. You burn a 16x rated disc at 4x it turns out to be a bad burn, which like others here I believe is the most probably the cause of the problem, and you come to the conclusion Verbs can’t be trusted. Even with a bad batch I seriously doubt that they would degrade that quickly. I have never had a G05 degrade that quickly and and my 4x verbs are still readable now. Verbatim are second in reputation only to TY.
I’ll try a little experiment and post the results later with burning 16x Verbs both + and - in my BenQ and post the scans later. It will atleast add another drive to the equation and see if the marginal burns mentioned by Frank are drive dependant.
By the way you mentioned Maxells, what is the rated speed of those discs and what speed did you burn them at?
Santa they will only replace the discs if it is a problem with the discs and the problem is not caused by the user themselves. Taken from verbatims own site:
*** This media is compliant with the new standards for 16x DVD+R recording. However, using this media with the lower speed DVD+RW/+R drives that do not support higher speed recording speeds may result in writing errors, failures in retrieval of data, or damage to the data recorded on this media. Older drives might require a firmware upgrade, so please check with your drive manufacturer.
The same is there in the -R section too.
After a quick look at the pioneer site I have chaecked on the support of the 107 for 16x media and it does say that support for this speed of media is “unique to the drive” which if I am correct means some drives will support and some won’t. Not exactly a definative answer. Maybe contacting the manufacturer with the serial number of your drive will gat a much better answer than what I read.
Also I don’t think that because you are using the latest firmware will help I have just checked the date of that firmware and it says September 2004. Which is a long time ago and well before 16x cam out.
