KProbe/PlexTools Scans - Page 1

In the following screenshots you can see the PI/PIF scans for the media we burned with the Plextor PX-712A. The software we used for all measurements is the KProbe v2.1.0, and the reader is a LiteOn LDW-811S with "patched" firmware, being able to read DVD±R/RW media up to 8X CAV. All scans have been performed at 8X with PI/PIF Sum8. Note that LiteOn drives cannot report PO but PIF errors, despite what KProbe reports. In addition all discs have been scanned with PX-712A v1.01 using PlexTools v2.13 for comparison levels.

Comparing the KProbe/PlexTools scans we can see major differences at the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combination, scanning at different reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). Its interesting to see the disc scanned at low & high speed, since when the error rate increases at a specific disc area, it should appear in both scans...else it would be, perhaps, a reading glitch of the tested reader.

Note: PI/PIF errors only give us a quick look at the error rate of the burned media. Those scans should be taken not as the asbolute criteria of the burning quality but as an indication level.

- Summary

Most of the 4X DVD+R media burned at 8X without any serious problem. The reported PI/PIF error rate is low and most of the problems are focused on the outer area of the disc. The 12X DVD+R writing speed shows very good results, mostly with TY based media.
