I've been using testdisk was well, but in this specific case,
it wouldn't help. All those tools rely on the OS performing
the (block) I/O operations, and if the device says "end of
medium", they stop and never reach the _actual_ data which
might or might not (!) still be there somewhere in the
memory chip, guarded by the card's controller.
There are even more sophisticated recovery tools (refer to
my "big important list of recovery tools" posted occassionally
on this list), but I fear none of them would be any help here.
