if you shave no system error showing any evidence you are wrong here -
even if it would be true witout any errors message you are wrong here
because it's the same as asking if your neighbours dog pissed on your wall

even with a filesystem error you are wrong here and it's impossible that
the raid forget about exactly one folder because that layer don't now
about folders and the FS would puke if a complete area desiapperas at
running fsck - period
