problem with ntlm hash

[jeffunit]

I am trying to break ntlm hashes. Hashcat doesn't seem to detect the hashes.
Here is my test ntlm hash file:

fffffff89c38368724b98c4016622476
fffffff439e17f169bbb2216d9c4e4e6

I am using  windows 10.

Here is the command line and the result of running it.

password-cracking\hashcat-6.2.6>hashcat.exe -m 1000 ntlm_sample.rawest ..\dictionaries\rock.dic

Why can't hashcat detect the NTLM hashes?
