the clip arrived, I dumped twice and they are identical, here is the dump
http://rghost.net/8wDm4C2FR
I wrote a script to print hashes of every 1M chunk of the dumps:
$ node chunk_hash.js dump/32.dump.1.bin
input file name: dump/32.dump.1.bin
chunk size: 1048576, hash: sha256

turns out the first 3M of the FPT dump comes from the later 3M of 64.dump.1.bin and the later 4M comes from 32.dump.1.bin but with 1 byte difference
