Accuraterip no match with confidence 1

Hello,

I have a question similar to the one a few topics below. I have a CD which is only in the AccurateRip DB, not in the CUETools db, and the AccurateRip confidence is only 1. All tracks are a match except one. I have ripped the cd on 4 different drives, 2 difference machines and almost always get the same CRC. One drive sometimes gives another CRC, sometimes same one as the other ones. In any case both are different from the one in the DB. There is some error correction being done in secure mode. I also tried paranoid and burst modes without c2 correction, all giving the same result. It is safe to assume there is only one pressing as it's a limited edition of 2000, never re-released.

How can I know whether my rip is fine or not, or if the rip in the database is the one having a problem? I can post logs, just tell me what would be useful.

Drives on machine 1: Optiarc 7260S, Pioneer BDR-S09
Drives on machine 2: Toshiba SD-M1612, Plextor Premium

thanks!

almost always get the same CRC

Doesn't inspire a lot of confidence that the rip was accurate.

Time may tell.
