Situation: For years (probably 8+) now I have been ripping my CDs to MP3 and added the albums to my library. Within the past 6Months I have switched over to FLAC as well. Problem: Over the years especially older material has been copied a few times (HDD upgrades, etc..). I find myself with audibly corrupted / faulty tracks every now & then. (The current drive is without problems as far as I can tell.) What is the best approach to detect, or even prevent this corruption? I have tried programs which are supposed to detect corrupted MP3s. My impression is that they show many false positives. Perfectly ripped tracks are shown fine in one scanner, bad in some way in another Maybe checksums are the way to go once I ripped a new CD / re-ripped an old one. Would there be any benefit in having MP3s archived (RAR)? Neither my player, nor myself care. Obviously there is no gained space. FLAC - Archives become huge and unpacking when dropped into player takes time. Is there a way to auto-check a corresponding checksum file if an archive is extracted for play / or unpacked songs are dragged into a player?
