Sorry, thinking about it, that would be valid for the case without '-o 
sync' where write operations do not happen right away but are buffered. 
But in the synchronous case writes should be performed more or less 
immediately.

I was thinking along the lines of misconfigured hardware or software 
believing that there were bit flips in the data and it needed to be 
rewritten for that reason.
