I dont know
Model match
Mix is OK. You can check with "Sector" number. Every sector goes in sequence
Xor is OK. FAT32 -> Compare tables do not show difference
Some files is OK

I wrote a script to properly assemble the image..
It's basically a Sector Number Slow implementation
(BN * Block Size) + (Sector Number * Page Size)
Top to Bottom...
There were a lot of blocks that contained unordered pages which is why none of the files opened.
99.5% Recovered..

Can use "bn to sn" to work with SN Slow

Yes. I try it now. It works
But very uncomfortable
Scan works fast
But Open Image very slow
Uncomfortable check files
Can not fix conflicts
Also many paremeters. So can make errors
Better use SN Slow

If only a solution had presented itself before I wasted my time writing an assembler when I described the problem

Won't this method assume pages are out of order in a single block? The issue is pages are missing in a single block AND out of order. This is why bn to sn was needed. File structure appears to be okay but almost all files are corrupt.

Yes
Raw recovery test:
SN Slow: 169 good, 84 broken jpegs
SN Old: 159 good, 79 broken
