Arduino with SD Card

I am not the first or the smartest to record my Arduino projects.  But I'm writing this so that even if it helps none of you, I can save myself four hours next time I decide to get out a certain part.

Components Used:

SD Reader from FastTech: $2.88

Resources:

I downloaded the latest version of SD library from adafruit's github

I followed instructions from adafruit

I had a look at the Arduino SPI reference and looked at the SD card notes

I found Profmason's site useful too.

Once the wiring is right try the cardinfo example from the SD library and it should work!

Problem:  I got all the wiring wrong because I have a mega.  

Solution: follow the wiring in the CardInfo example Source

Problem:  My card didn't work

Solution:  It was an MMC card, it needs to be FAT and SD
