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

It's this:

if(sector[0x10] == sector[0x14] && sector[0x11] == sector[0x15] && sector[0x12] == sector[0x16] && sector[0x13] == sector[0x17]) { OK } else { FLAGS_NOT_SAME }

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

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

Code: Select all

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

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?

Better not to, due to /viewtopic.php?p=38722#p38722 at least.

I find for psx-j that:

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

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

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