Please take a look at this scan. But for the crap at the beginning of the scan, this would be a good one. What besides the disk causes the high errors at the beginning of a scan? Does the beginng of the scan correlate with the inner tracks of the disk or the outer tracks, or is there a correlation?
I had that kind of errors increment with my DH-20A4H on Maxell 003 media but at the end of the disc not at the beginning like in your scan. I my case decreased the write speed totally solves the problem. also online hiper tunning (don’t know if your drive support this) helped.
then try burning at lower speed.
