Noticed 3 parity errors in one of the checks.  Ran it a second time just to see if it was a one off occurence, but got the same 3 errors again.

 

Ran it a third time with "Write corrections" checked but although during the check it said something along the lines of "Corrected 3 errors" (can't remember the exact wording now), it has finished with 3 errors again:

That's normal if the previous checks were non correct, next one should find 0 errors.

A correcting check treats the sectors it corrected as ‘errors’ in the end notification.   As was mentioned the next (non-correcting) check should now find 0 errors).
