hi Sergei,
have a test file (I had some problems with this when attempting a full recovery)..
I have
File size: 1 GB
Mix removed: Yes
Block size 0x84000
Using the above I can see the JPG headers in HEX viewer, but when using the viewer section, I get errors;
'Unexpected Marker 0xnnnn at 0xyyyy'
OR
Out of Buffer
When clicking 'Next' I get 'Data Corrupt: JPEG Load State not valid'
I tried the above after converting to RAW but the Headers are now wrong.
For the JPEG Scanner Parameters I used
Cluster 0x0
Block size 0x80000
I also tried with Block Size 0x40000
(Is the above supposed to be the cluster' size ? Or is the block size as in NAND ?
Nothing I try seems to give any good information. It is something I am doing wrong - I know it

1. Cut SA with Dump_Converter / RAW
2. Delete old scan result (JPEG_Scan folder)
3. Set Block_Size in params
Block_Size = 0x80000
0x80000 = 0x84000 / 0x210 * 0x200
(we cut SA)
Leave Claster_0 = 0
We use it for originaly fragmented file recovery.
Check_Size = 0x4000
then bigger - then better quality, but slowly

Thanks :)
Note: Files move from folder to folder
When:
- you work manualy and press "Apply"
- on every step of "auto"
