Formatting under Windows/Mac

If you bought an SD card, chances are it's already pre-formatted with a FAT filesystem.

However you may have problems with how the factory formats the card, or if it's an old card

it needs to be reformatted. The Arduino SD library we use supports both FAT16 and FAT32

filesystems. If you have a very small SD card, say 8-32 Megabytes you might find it is

formatted FAT12 which isnt supported. You'll have to reformat these card. Either way, its

always good idea to format the card before using, even if its new! Note that formatting will

erase the card so save anything you want first

We strongly recommend you use the official SD card formatter utility - written by the SD

association it solves many problems that come with bad formatting!

The official SD formatter is available from

https://www.sdcard.org/downloads/formatter_4/ (http://adafru.it/cfL)
