I see now. I have only created image with ECC = off, because dump is already ECC-corrected.
Please explain this situation.
I will save new image and check results.

Saved new image with ECC = check.
It made a big difference. I've got full file system structure now, ExFAT

Good news!
Why this happen:
Some sectors with wrong or system data have red ECC
It will help filter this sectors

What you mean by "ECC optimized"?
First we make ECC Fix
After it we save image
We get different results with ECC = Off, and ECC = Check

Optimization like best RR, and best voltage to get the cleanest read
