If you can run SdFatInfo it would be interesting to see what it prints.

Here is how to do it and an example of a counterfeit card:

You can run it on any shield or breakout with a SD socket.

Thank you richms!!

I was getting ready to order some incredibly cheap 1 Gb SD cards direct from Hong Kong.......

Thanks for the h2test also. In my 'Bag-o-tricks'

Back to the SD Card Card "Breakout", may I invite you to drop an eye here? http://didier.longueville.free.fr/arduinoos/?p=683 . The simplest the best :wink: , as long as we talk about quick (but reliable) prototyping. And the cost is ridiculously low.

Next suggestion would be to design a user interface breakout with LCD and rotary encoder... (just like this one may be http://didier.longueville.free.fr/arduinoos/?p=643 ?)

you can drive nearly all SD cards like that...but we have found some really need to have a buffer, not resistors, or they have errors. also the 3.3v regulator in the ftdi is good for about 40mA but some cards require 150mA or more to write. basically you could write the card and it would -probably- work but possibly cause you to lose your USB connection.

Point taken Limor. But believe me, I had an almost pro approach to the question of testing, and the "resistors solution + 3.3 FTDI" worked without the least error on standard SD cards and thousands testing loops (just like in the proposed example attached to the library).

Again, this solution is appropriate for quick prototyping, but I would not encourage the use of it for medical/military grade applications :wink:
