Praise The Almighty, I just made a wish for such a thread a few days ago in another thread, and it came true within twenty-four hours. I thank you and the moderators for doing so.<O:p</O:p
The comparisons between different devices in disc quality testing are most welcome and long awaited. This is an excellent article for amateurs. However, there is still room for improvement.<O:p</O:p
First, the average values reported by some of the testing programs are incorrect. Plextools erroneously calculated PIE average as SUM1 even though SUM8 was indicated on the graph. It is better to use PxScan in this respect at least. On the other hand, KProbe 2.4.2 miscalculated PIF average as SUM8 even when SUM1 was chosen for scanning. To get correct results, KProbe 2.4.0 should be used instead. Although Nero CD-DVD Speed may also be used in this case, its PIF averages are also incorrectly calculated when the scanning interval is different from the sample length. Although average values are not the most important numbers in error scanning, it is preferable to be correct in an article aimed for excellence.<O:p</O:p
Secondly, the scanning speeds used in the cases of LiteOn and the Philips drives gave the highest possible PIE/PIF counts by each of them, whereas the speed chosen for Plextor drive gave the lowest counts. It is better to use 12X or 8X with the Plextor's.
As I have stated in the thread mentioned above, I am also doing comparisons between CATS and some PC drives, and I hope that the same parameters are adopted to make it easier to read different reports.
I shall post more critical comments later if your team do not object.
