you ever seen pioneer scan from 108 109 or 110 , ya they scan too, and let me tell you what comes out of those drives is totally messed-up. I did test sorry no scans to post, as erased them they were so different, from pioneer scan you would have thought the media was 100% crap and a coaster, from liteon 1693 the pie level never went past 10 and pif level was like 2.5, but pioneer scan pie level 1000+ many hills across the scan and the pioneer scans pio not pif so the pio graph was 100+ and hilly too.
