I accidentally formatted a 4gb sd card to FAT32. Now I can't use it in any of my digital cameras. Any way that I can change it back? All of my cameras say "this card cannot be read/used", or something along those lines.
I'm using OSX btw, not window if that makes any difference.
Never never never never format your cards using your computer, Mac or especially Microsoft based. Reformat in the camera. Microsoft loves to screwup memory cards.
Walt I don't doubt your own experience but I have formatted CF cards in a card reader (Windows) since I got my first DSLR in 2003 and never had a problem. All my DSLRs are/have been Nikon. OzJohn
