The Unix/Linux convention is that programs don't print anything if
everything is working OK.  You could check the program exit code if
you care.

Is this an SD card the came from Matt or something you picked up some
place else?  My understanding is that not all brands of them work
(something to do with the required logic levels).  FWIW, Matt's been
shipping "Patriot Memory" brand cards.  The largest size that will
work is 2GB.
