I upgraded the SD card from 1 gb to 2 gb. They are both SD, but the\noriginal one says "Filemate", whiile the new one says (in red)\n"Scandisk". Well, then new card DOES NOT WORK. THe camera says the\ncard needs to be formatted...but when you attempt to format, you get\na "file sys error" code #, and it shows a frozen hour glass. Has a\nred flashing light as soon as turned on, too.\n\nThe manual shows photo storage capacities, and it only goes up to 1\ngb. But at the bottom it says that if using over 1 gb, the video will\nstop, and you have to restart it. So it sounds like there isn't\nreally a limit of 1 gb. card size. I tried this new card in a Kodak\nC310 also, and it does exactly the same thing. Is it just a bad\nmemory stick? What is the top limit for SD card size? Is there any?
