Error checker for FLAC library?

[davide256]

Just had an issue where my backup library had some corrupted FLAC files, now  I want to check all just to make sure no more are lurking in source or backup directory. Any good programs out there that do this?  Also wondering the same now about DSD files...

PlayPcmWin installer package includes FlacIntegrityChecker program.

It is installed on C:\Program Files\yamamoto2002\PlayPcmWin64\FlacIntegrityChecker

 

 

 

Thanks, will give this a try. Trying to prep now for a NAS HD size upgrade and want to be sure that I catch any bad data.

 

Roon checks tags when you add to your library, was able to find that something happened to albums starting with "E" in the backup. But

that check wont help if corruption was outside the tag...

Running now, will see how long 7300 files takes 😁

Not bad for time and I have a few to fix  👍

 

Need to do this next against the NAS, suspect thats going to take far longer. Having something like this to run regularly for the NAS

seems like a good idea

So this was across Etherregen switch, gige connections, completed slightly faster than like local HD scan. This will work.

Had something weird happen. Roon identified 3 files as bad last nite, I overwrote them with files from the NAS that were verified good on NAS today, bad on HD

would swear they played after overwrite last nite but today they were bad again. Manually deleted, purged recycle bin and recopied, they play now.

Will check again in 24 hours.
