Oddities between burners....

[kenmo]

I have the following DVD burners

LG GSA-4160B
LG GSA-4167B
Pioneer DVR-105

And I've been testing some old DVD media that was burned 4 years ago on my Pioneer. I use Nero's CD-DVD Speed Disc to scan these old discs... I'm doing surface scans and not file read....

What I found is most of these older discs will fail on my LG 4160B but pass 100% on my Pioneer or LG 4167B.... I find this most odd....

The Pioneer and LG 4167B are on the same computer....

Any ideas on this? Should I be concerned...

Thanks muchly

Based on the assumption you are referring to the ScanDisk function (not DiscQuality) then your findings aren't necessarily a concern. This test is relevant only in that it rates the drives ability to read the disc in question. Many drives are pickier than others. Green blocks mean the sector is perfectly readable. Yellow meaning readable - but only due to internal correction error capabilities of the scanning drive. Red blocks mean damaged sectors that contain uncorrectable errors. If two drives report no errors and one does then I might suspect the drive is dirty - defective or just flat a poor reader. Are these DVD Video or Data? If video - do they play okay on set-top players?

Video dvds... I haven't tested them in a dvd setop player yet...

It is also suspect that the one DVD burner that had issues with reading is on a different computer whereas the two DVD burners that read A-OK are on the same computer.

This sorta implies to be the possibility that the computer with the DVD burner that has reading issues could have issues itself. For instance maybe the DVD burner is hooked up correctly or has gone into PIO mode instead of DMA mode or there is an incompatability issue of some sort or a OS issue or ... whatever.

If you have the time and inclination it might be interesting to take the DVD burner with reading issues and put it in the other computer (replace the Pioneer or the other LG) and see how it works on that computer when it comes to reading these DVD discs.
