ZFS can mostly handle that. It will try to recover any data it can, and rebuild whatever it can. Due to how paranoid ZFS is designed, it will survive edge cases like this much better, which is also why I like deploying it here even at home.

And if it can't recover it? You can prove it by failed checksum check. This is why, in my opinion, ZFS is so much better than all other file systems: if it fails, you can prove it instead of just sorta vaguely questioning everything because you can't tell but you suspect it, and it slowly drives you insane.

Once you try ZFS, you never go back.
