I see you've concluded the ncks md5 hash feature solves your problem.
I couldn't help noticing you'd found the script I wrote
https://github.com/aidanheerdegen/nchash
This is an attempt to perform an initial sanity check on multigigabyte 
netCDF files with runtime independent of size. 
I can't blame anyone for not understanding it's purpose, as there was no 
documentation at all. I have now added a README.
Cheers
Aidan
