Pedroski55,
Thanks for the reply.
i fear that the foundation I've been thinking about building is weak, reading the whole SD in, and resolving endian for 65536 sectors of read and byte swapping at one time.
Can python read one targeted/indexed (I.E. sector #1 or #x) sector of the SD at a time?
I only need to resolve sector 1 (MFD master file directory, think root) , the sector 2 - 9 (BITMAP think bitmap of sectors in use), a couple UFD sectors (user file directory, think first and only user-file directory-level), and however many sectors the target file uses. less than an average of 20 sector vs 65536 seems better.
without having to understand stone-age file structures, processing an average of 20 sectors vs 65536 seems obvious, is there a way to read sectors?
