I gather you mean you're trying to SHA1 sum a large file on an SMB share?

I've seen similar tee'ing a dd image through md5sum/sha1sum over a
network, and also large files on slow media (CF card).

I suspect the only way you will get consistent results is if you run
them on local data (i.e. copy the image locally and run it or
alternatively run it on the machine which stores the data)

Best Regards,

Morgan
