I could use some help getting an SD card working on an Arduino. I'm following the tutorial below and using the example code from the Arduino IDE.

99% of the time it's telling me the wiring wrong/no SD card error. 1% of the time, it says the card isn't formatted.

I have the CS pin correct in the code.

Has anyone seen this before? I've swapped card readers, Arduinios, wires and SD card readers. I'm not sure what I'm doing wrong.
