 Yes, OK I guess NTFS would be of most interest to me.

Then you'll have a hard time because NTFS specs are not available for
free.  Just reverse engineered stuff.

   Uh... this is highly OS dependent... You need to be able to do
 direct RAW disk sector addressing; something that OSs don't really like
 to give to applications. You also need very good documentation of the
 file system (and the only file system I know well enough to navigate at
 that level is one I haven't used in over a decade -- the file system
 used by the Amiga, which was a hashed-head, multiple linked list
 scheme).

Yes, OK I guess NTFS would be of most interest to me.  From the
research I have been doing it may be that it is a fairly in depth
undertaking and possibly not such a good project considering my
knowledge of NTFS and python.  I will have bit more of a look about.
