 Bigger Bigger  Smaller Smaller  Reset Reset

I worked on this very same issue for a month, read every post on every forum I could find,,,bought several brands of sd cards, never got it to behave. I got all the same error messages. The one time I thought it worked, it never worked again.

I bought these for less than $3 ea for 3:

Hardest part was getting the nerve to try them out, worried about 5V vs 3.3V. Next hardest was getting female to male jumpers. After that it was write enough sketch to see the module report back okay with a 2G FAT-formatted SD card in place. Then write enough sketch to prove the rest.
I didn't start by writing extensive code........

I needed both SPI and sdFat libraries (SD library with SPI library works too).
