It seems to blindly try some modes until something usable is found.
Varying

This thread says that only the first 1024 bytes of data (+ 96 bytes of
ECC) of each page are used:
yes I am sure. There was no page access commands between the sectors,
only linear read of data,ecc,data,ecc.
Hmm..

Not really. It's only a little different (sequential ECC, static
randomizer seed on every page).

I tried many things but did not quite get the ECC reading command to
return meaningful resuts. But should work
