Make sure you include Manufacturer, Model, Size, and how it was formatted. (In Particular you should try and post the cluster size, and whether it is FAT16 or FAT32).

I will keep this post updated with a list of Cards that have been tested and posted to this thread.

With these results it should help people who are thinking of buying a card for the 700p.
