No I can't. My camera only uses ExFAT on sdxc cards.I can't add Ext2 No, it's a stupid idea. Ext2 is passable although I would have to buy some really **** software for my Mac. Ext3/4 on sd cards is silly. They wouldn't be so daft. And if we're being anti M$, can they please stop paying to license Exchange ActiveSync and put the money to fixing the open standards... CalDAV, CardDAV and improve their IMAP support.
