I can't find marker. I found FAT32 after byteswap but no fat-tables. There is also a lot of readable text in dump. Any suggestions on how to proceed ?
See file 300k put on ftp, sandisk_no_marker.rar

This controller have some differences in algorithm.
I hack one some weeks later.
I need more dumps to make universal util.
Put full dump on ftp
And i help recover data.
Before you send dump!
Make experiment.
Split by dump (2)
Compare result dumps.
If they identical half MB in config.
Repeat.
Try read id in 2,3,4 banks.

Flash should be PC formatted. Customer have only PC. I know that it is 2 partitions by default on these memories. One that autostarts with sandisk utilities.

This chip was from an SandDisk with a physically broken PCB. I moved the controller and memory chip to another pcb, and it works. It is FAT32.
Can i do something that helps further analyzing of this controller?
