That's the good news!

This message means that the filesystem has detected some sort of
inconsistency, but you don't have to worry in your case; the error
flag can be marked imprecisely when a filesystem has detected I/O
errors even if no inconsistency occurs.

This flag is not cleared by fsck0 because I haven't yet implemented
the feature which fully verifies coherency of a filesystem. ;)

Well, if you can't ignore the message, I can add a dummy force check
option that does nothing but drop the flag.
