@Frank1940 Yes, I agree.. I would never use this disk with those many errors.. It's in the pile marked as "Defective" and is going to the recycling center next time im going there..
One thing is strange though. The report for this disc tried to upload as usual to the developer of the plugin, but upload failed. I tried like 3-4 times.. All other reports (like 10-15 reports) have reported just fine. This is the only report where the preclear plugin did not run to the end.
