SD card fails to initialize
The first thing to try is to use the 'proper' pins for the SPI:

SCK to Pin 10 on Arduino ---&gt; Pin 13
CS to Pin 11 on Arduino ---&gt; Pin 10
MISO to Pin 12 on Arduino ---&gt; Pin 12
MOSI to Pin 13 on Arduino ---&gt; Pin 11
VCC to 3.3V source on Arduino
GND to Arduino Ground


Try that first and see how you get on.



By the way, just thought I'd mention, probably worth just following the Adafruit example word for word as I'm guessing your board is pretty much a good fit for this tutorial:

good luck getting it rockin' ;)
