Somehow my microSD Shield had a connection problem on port D3 and the 3.3V port. <br />
After getting card.init errors I did much research and thought it might be a pin (SS_PIN 8 vs 10) or SD card problem (2GB card). After much digging I fortunately then realized that the power led wasn’t on! Soldering on the 3.3V header pin looked good but no connection and even after re-soldering the connection between the header and the board was still not there. So I had to create an extra bridge between the header pin and the board.<br />
Hope this was due of some user error or was a one time production error.<br />
Just make sure the power led on the board is ON before digging into any other troubleshooting.
