Hmm... would be a surprise, since I copy loads of data over that machine, which is always protected by some SHA512 sums. But could of course be possible. I assume you mean the bitflip would have happened when the data was written? Cause reading it reproducibly causes the same issue. But shouldn't a scrub have noticed that? That file was created around January 2019, and since then I've had mad several scrubs at least. > Please run memtest on the machine. Will do so later. Anyway... is it recommended to re-create the fs? Or is deleting the file enough, if a fsck+scrub finds nothing else. Thanks, Chris
