I have canon digital camera with which i took some photos last night. Now when i connect memory card of digital camera to computer it says i need to format the card before using it. Then i inserted my card in to digtal camera i was surprised to find camera saying no memory card. My friend says i need to format the memory card if i want to use it but he also told if i format i will delete all photos from memory card. I dont understand what to do? I want the photos from memory card.
