The C330 uses MMC and SD cards. Your 4GB card is actually an SDHC card. While SDHC cards will fit into SD slots, they are electronically incompatible and won't work. You need to go with cards 2GB and smaller.

Buy a 1GB card (or 2). The spec for the SD card format is going to 2GB but the Kodak C330 not compatible with 2 GB SD memory cards.

try doing a format with the camera. check your manual to see how to do this with your camera. Beware, formatting will erase anything on the card. i actually had the same problem with my camera, and this worked for me. Sometimes new flash cards are not compatible off the shelf--they need to be formatted. You should have at least flash cards to be sure card is not defective. Let me know if this helps!
