http://www.flash-extractor.com/library/Monolith/Micro%20SD/Monolith%20Micro%20SD_3/Monolith%20Micro%20SD_3__ec_de_d9_ca__2x1

but if this is true:
Quote:
Device is xored
Xor applied before ECC
Xor depends from block number
Block number is located in translator table

Cant find translator table
Cant remove XOR
Thats why ecc map is red


why can I find FAT?
