Ok, so i came up with the idea of using the m? functions for dumping the data (what is the difference between those anyway?), into a huge file (you get 80bytes for each 16 bytes of data, so 160MB for a 32MB model and a hellufa lot of time, say 4 hours at 105200), and than parse these back to the original 32MB, based on the hex dump supplied.
As to your question, for which i'd like the answer myself, about the file system: as it's windows, i hope it will be some form of FAT or NTFS, but what i've seen so far, i'm afraid it's the system MS developed for storing their office documents....
Does anyone know if parts of the data are stored encoded/crunched/ encrypted?
