i have loooked in some of the nice links i got to read about c1 and c2 errors

but i have one question that is unanswered

are c1 errors
a: errors that are corrected by the c1 level of error correction
b: errors that can NOT be corrected by the c1 level of error correction and must be descrampled and then corrected by the c2 level of error correction


I read somwhere that c2 errors means that it has to be correted at the extra ECC the data sectors have, and if it was audio the error would be interpolated.

If that is the truth then c1 erroes are erroes so grim the the first level  (c1) was not god enogth to correct them.
I'm then conserned about the high level of c1 errors my burnings get (around 800-1200) but still get 98% quality in Nero CDspeed

Feurio and EAC are conflicting. EAC says that drives return uncorrectable C2 errors (that are CU errors), and Feurio says that they return plain C2 errors (that are uncorrectable C1 errors). I've been told, but I can't check it, that it depends on the drive, because there is no clear standard about the C2 error info returned by drives.

Plextools return C2 and CU separately. Thus it returns correctable C1 (otherwise they would be the same thing as C2, since C2 is below CU). Other drives certainly return correctable C1 too.

So it kinda up to the drive if a c2 errors reported is a c2 uncorectable or a c2 corrected ?

damn i hate nonstandard stuff :-)

The DAEquality tool on the EAC website can help you find it out.
If your drive reports only CU errors, the second curve should be very low. If it reports all C2 errors, the second curve should be proportional to the first one.
