This is pretty good! Detecting bitrot is fine, can also be done by storing a MD5/SHA256 of the file content. `md5sum <file>` barfs if its unable to read the file from disk. Challenge is rebuilding the broken file. I was worried about bitrot on my old external drives too. I eventually went with btrfs[1] filesystem running RAID1 across 2 disks.

Adding/verifying hashes on media might not be a bad feature to add for those who don't want to burn the extra space required for PAR2. I run w/two extra parity disks on unRAID, but I'm too paranoid to leave my data at rest without an extra file-level of parity.
