KProbe PI/PO quality results

The following screenshots show the PI/PO scans for various DVD-/+R and DVD-/+RW media, recorded with LiteOn SOHW-812S at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.28, the ECC was set to 8 and the reader was LiteOn LDW-811s. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Hence, we cannot safely come up with conclusive results, although we do make a comparison of the drive behavior when using various DVD recordable/rewritable media.

The recordable discs we used, came from Verbatim, Taiyo Yuden, CMC, MAM, Maxell , MC and Ritek. Further details about each disc type are presented at the bottom of this page.

Kprobe reported that the PIPO mesurements with LiteOn written DVD media are high. After the end of he tKprobe mesurements we used NeroCDSpeed to read the discs that reported high PI/PO errors. The only disc that was not readable was the CMC DVD-R disc.
