I am in the process of re-ripping all my old CDs to FLAC with Foobar. I had the software look up my CD drive, and it appears to have found the drive and set an offset. The CDs themselves are old, so they're not in perfect condition, but they are generally OK.
Every CD so far has ended with a window showing that a few tracks were "Not Accurate" after a few "Retrying".
How big of a problem is this?
