yes, sorry that I did not make that clear. I am interested in writing data to an SD RAM card for my next project. I have no experience with C or a compiler, only assembly however all the examples I found were in C. I don't mind writing it from scratch but would rather not if it is available. I'm really not so interested in the details on how it works as opposed to just wanting to get it working as quick as possible. Thanks for all the links posted, I'll have a look at them now.

You mean specifically WRT implementing FAT, right? That wasn't very obvious... BillW _________________________________________________________________ Experience the magic of the holidays.
