keigo_kanzaki Posted March 11, 2012 Posted March 11, 2012 (edited) Hello, I've been using ImgBurn for several years and I like it. However, I do have a question: sometimes (not always), when I'm burning something on a DVD+R with my Pioneer A12FX drive, the burning speed suddenly got dropped at certain percentage, then it got back on again. I use the "verify" option too after the burn, and the results are normal (I think, since I've got no error report). I wonder what could cause the speed drop? Here's the detail: media: Verbatim DVD+R Made in Japan (16x) write speed selected: 12x OPC: ON drive: Pioneer A12FX (IDE) OS: Windows 7 RAM: 2GB Also, I captured the graph data: http://i34.photobucket.com/albums/d115/keigo_kanzaki/PIONEER_DVD-RW_DVR-112_128_THURSDAY-MARCH-08-2012_6-25_PM_YUDEN000-T03-00_12x.png As far as I know, this happens only when I'm using Pioneer A12FX (listed as DVR-112 here). When I use the other drive (Pioneer DVR-212 SATA), it never happens. I want to know also if this affects the burning quality, which means I should make another copy.

LIGHTNING UK! Posted March 11, 2012 Posted March 11, 2012 That's just the drive performing its own quality checks as it goes and adjusting the laser power accordingly - in order to achieve the best possible burn. Seeing as the 112 and 212 are basically the same drive, I don't know why it wouldn't be doing that too... weird. Different firmware perhaps?

Well, I'm glad that you confirmed nothing's wrong with the burning process. As for the different behavior between those drives, I don't know either... But as long as the burn quality is good, that's fine Thank you for your reply, LIGHTNING UK! Edited March 12, 2012 by keigo_kanzaki
