I use BTRFS for the same. Being able to check for and repair silent corruptions is a must (and this is without needing to read the whole drives, only the actual files). I’ve had a lot of them over the years, including (but not only) because of a cheap USB controller also.

Great project !

Naming conventions are missing some important information like bitrate, color depth, and most importantly language and subtitles.

Do you plan to scrape additional infos from known torrent sites (searching for torrent hashes for well named torrents) ?
