Hey Hein,

You could take a look at http://www.sf.net/projects/efsl, a library that
provides read/write access for FAT12/16/32. There are backends for
various platforms, including AVR ATMega + SD-Card. Take a look at the
stable branch (0.2). It also contains a manual with a "Getting Started
on AVR".


Good luck!
