Those cases are an exception. Anyways, CDmage is way more worse, it is counting WARNING cases to the total errors count.

Then you should either rename it to "errors/warning", "unusual sectors" or something similar OR to add the "warnings" field as well.

From when? If the error counts of CDMage isn't adopted forever, I think the old dump that has errors should be rechecked. Or already rechecked?

A long time ago, 1-2 years. The old values weren't rechecked i think, but we would only have to recheck discs with errors count > 1

See above

edccchk v1.26 errors+warnings count = CDMage error count

Not really. I have extra updated the submission form text with "Errors count (edccchk v1.26)" to be used with.

Better not to, due to http://forum.redump.org/post/55408/#p55408 at least.

but redump db adopts that of CDMage

EdcEcc  > [ERROR] Number of sector(s) where user data doesn't match the expected ECC/EDC: 1

edccchk > Total errors............ 1

either one or the other should be used

NO CDmage

EccEdc adopts the errors count of edccchk, but redump db adopts that of CDMage. http://redump.org/disc/327/

And edccchk (for comparison)? I'm not sure what does "flag byte doesn't zero" mean.
