If I rip a track in secure mode (Hitachi GD 2500, accurate stream, no cache, c2 correction) and during the rip process the correction indicator gets higlighted and then continues ripping. The EAC report indicates “No error” but when I hear the resulting wav file there is an error in it (a blank at the position where the correction indicator got highlighted)! The rest of the track is perfect of course. There is only this small blank.

It seems that C2 is not correctly implemented in some drives. To be on the safe side, you should turn off the C2 error correction.
