First, why are you not using file but whole partition?
With file you do not need to use -s.
(See man page, read is exhausting for key, so

-s takes size in bits (multiple of 8 bits only), so 1216.

See man page "notes on password processing".
(Also check --debug output, maybe there is some more info.)
