Alcohol 120% is unable to dump into ccd/img/sub, all the audio tracks become shifted. Unless that was fixed in the recent versions, but I have doubts.

Meh? What pregaps, what cuesheets? You've just said "ccd/img/sub". And what errors?
Rallye89 wrote:i tried also sbi2sub utility but seems to generate altered data in the last sectors of sub file, maybe it's the pregap?).
Depends on the differences.
Rallye89 wrote:What exactly i have to do with cddas and error count different from 0?
RAW DAO 96 burning mode shouldn't affect those errors and leave them intact.

You can try to check the swap trick, whether it works for your drive or not. Find the "startstop" utility somewhere on this forum, insert any Audio CD, stop the drive, eject the tray by inserting some pin into the emergency eject hole, insert the game disc, close the tray manually using some force, then try to read the sectors. You should see the scrambled data sectors in the data area.

Images with CDDA differ, if dumped with CloneCD or similar, since they don't do the offset correction. Subs won't match, either, since the dumping tools don't correct the random errors.
