This is a major pain in the ar$e that I have not found a solution to.
The only solution I currently have to to keep buying random SD cards from ebay until I fluke some that work with the shields.
Someone out there is the huge Arduino community must have found a solution to this SURELY!
Formatting the cards with windows format, with disk manager and with SD Card formater app simply do not work with the the SD cards I have. Deleting patitions, re-creating them, formatting under as FAT volumes all do not work. Changing allocation sizes does not work.
The cards simply will not successfully initialise under the Arduino SD library.
Someone please give me another solution to this that works!
Software that DOES format them in a way will render them useable with the SD library. A list of SD card makes and sizes that are known to work with the SD library (like the RPi list of useable SD cards) Anything other then random purchases on ebay!
