Hey guys. It’s my first post here at cdfreaks, after browsing the forums off and on for some time now. What I have is a request for any “experts” we may have to analyze the results I’ve gathered while burning ISO images to Sony D21 16x DVD+R discs. I got them on a really god deal at Staples yesterday, and from what I have read, they are supposed to be good discs, but the results I have gotten are mixed to me.
I’m supplying a handful of images. A caption will be above each one. All burns were done using a LiteON SOHW1633S drive with the BSOY unmodded firmware. Burning software is ImgBurn 2.1. If anyone would like to recommend a better burning software package, I’m open to suggestions. The only restriction I have is Alcohol120. I’ve used it before and have had extremely poor results with it.
Scanning was done with KProbe 2.5.2, using primarily default settings 8/1 4x.
During the first test I did (results not being posted), which was at 16x, I had ImgBurn’s verify feature turned on. It came up with a handful of read failure notices towards the last portion of the disc. They were basically in the same area as the spike in the 16x results below, but much worse on the charts.
The information I’m basically looking for is:
[li] Were these discs at least a decent purchase for my drive (considering $24.99 for 100). Discs are Sony D21 MIT 16x DVD+R
[/li][li]Do you think 16x is suitable for these discs, or should I stick with 8x?
[/li][li]At either speed, would the resulting errors as shown in these reports affect usability.
I don’t mind burning at 8x. It really doesn’t seem to take much longer.
Control Scan, Done with used-but-not-abused original DVD.
Sony D21 +R, Burned at 16x
Sony D21 +R, Burned at 8x
Another control scan of sorts. Memorex branded, Ritek F1 DVD-R 16x, but burned at 8x

Remember that the Original and Riteks are control scans for comparison.
