If you don't want to re-rip everything in EAC just to make sure the rips are accurate, try Cuetools to verify your lossless rips against the Accurip database. It's very, very fast but it might mean monkeying around with your metadata to get it to recognize the correct disc. If your files verify against the database with good numbers, then you know those are accurate rips and you don't have to be concerned. This will let you focus on only those files that need to be re-ripped, which takes a lot longer than verifying, or even patch them without requiring a re-rip if the errors are very small. I've run my entire library through Cuetools and it's a great little program.
