Re: How many number of errors?

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

Re: How many number of errors?

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. http://redump.org/disc/327/

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


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 http://forum.redump.org/post/55408/#p55408 at least.

Re: How many number of errors?

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.

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

Re: How many number of errors?

"edccchk" won't list those rare cases with corrupted sectors or silent sectors as errored data sectors, they will be listed as "non-data sectors". And for discs with audio tracks in the current state it won't be possible to distinguish between audio and corrupted data sectors, as they are mixed in one line.
