Brute-force TrueCrypt non-system partition

Hi,

I've made a image from a TrueCrypt non-system partition with True Image.

I've made the following session:

oclHashcat64 -m 6211 -a 3 -n 32 l:\b.tib -1 '!' -2 ?d?l ?1?d?d?d?d?2?2?1 -o found.txt

If this wrong, is there another way to Brute-force a TrueCrypt non-system partition?

Thanks
