For checking exactly what the Sony DW-G120A reports, we used three different media, burned with other recorders. The three media have been measured with the well known AudioDev SA300 DVD CATS system at 1X.

The drive is capable of reporting PI/PIF errors, so we will compare those measurements at the 8X reading speed.

Please note, that the posted results are only valid for the specific tested DW-G120A drive. Using other drives, even another DW-G120A, can produce totally different results. Beware!

#1st Test Disc - PISum8/PIF Comparison - 8X Reading speed

From the above graphs, we can see that the error line trend follows almost the same pattern as the original CATS scans but the levels are different, especially in the PI sum graph.
