Memorex D² DVD±RW/DL Recorder - Page 13

In the following screenshots you can see the PI/PIF scans for the DVD+R/RW media we burned with the Memorex F16. The software we used for all measurements is KProbe v2.2.3 and the reader was the LiteOn LDW-811S with "HS0Q 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 can only report PIF errors and not PO, despite what KProbe reports. In addition, all discs have been scanned with PX-712A v1.04 using PlexTools v2.16 for comparison levels.

Comparing the KProbe/PlexTools scans we can see major differences in the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combinations, scanning at different reading speeds (8X CAV for KProbe, 2~5X CAV for PlexTools).

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 absolute criteria of the burning quality but as an indication level.

- Summary

Only a few media burned with the F16 had low PI/PIF levels. In most cases, both Kprobe and Plextools revealed high levels. This is something that has to be fixed. In many cases, Plextools reported errors which is mainly due to the Plextor drive being much more sensitive than the LiteOn.
