Hello all,
I am using mmc.frt and writing works very well. The problem is reading.
Bytes are clobbered in a consistent pattern with something else (see
below). I know the lc-tech sd card reader is not the problem because I have
tried reading my 16M SD card using my bus pirate without problems (
http://nada-labs.net/2010/using-the-buspirate-with-a-sd-card/ ).
Thank you for any and all clues!

The glyphs are stylized human, animal, vegetable and geometric shapes, and
often form compounds. Nearly all those with heads are oriented head up and
are either seen face on or in profile to the right, in the direction of
writing. It is not known what significance turning a glyph head-down or to
the left may have had. Heads often have characteristic projections on the
sides which may be eyes (as on the sea turtle glyph below, and more clearly
on sea-turtle petroglyphs) but which often resemble ears (as on the
anthropomorphic petroglyph in the next section). Birds are common; many
resemble the frigatebird (see image directly below) which was associated
with the supreme god Makemake.[21][note 4] Other glyphs look like fish or
arthropods. A few, but only a few, are similar to petroglyphs found
throughout the island.
