What kind of memory card does this camera take?

The XP10 works with SD cards, 2GB or smaller, and SDHC cards, 4GB to 32GB. It will not work with 64GB SDXC cards.

What device are you putting the card into? Is it compatible with SDHC cards, or only with SD cards?

The SD630 works with MMC and SD cards, 2GB or smaller. It does not work with higher-capacity SDHC cards.

Your SDHC card can be used in any camera that accepts SDHC cards.

A card that size is actually an SDHC card. SD and SDHC cards fit the same slots, but they are slightly different. Many cameras won't work with the SDHC (high capacity) cards. SDHC is not backwards compatible.

I expect your camera just won't work with this kind of card. It is often difficult to find out the maximum capacity memory card a camera will use, as today's cards are much larger that those available when the manual for the camera was written.

Remove the SD card from the camera. Slide the tiny switch on the side of the card to its other "unlocked" position. Reinsert the card in the camera. But if you've already tried this, see this link for additional things that you can try.

I believe this camera only supports SD/MMC cards, not SDHC cards. Go to the kodak site to see the detailed specs. Not all devices support SDHC - most new ones do - but some only support the older SD cards.

At 4GB size, your memory card is likely a SDHC card, and not a standard SD card. Although they look the same, there is a difference in formatting. Unfortunately your model camera was designed before the SDHC format came out, and it will not work with your camera. But fortunately standard SD cards are very inexpensive these days, and you should be able to purchase a good 2GB standard card for around $6 with shipping:

It will not work with any "sdhc"

Your camera will accept a maximum SD card capacity of 1GB. It simply isn't capable of handling anything of a larger capacity and in particular is incompatible with the more technically advanced SDHC cards.

Your fix is to either replace your camera with a later model or to stick to using SD cards with a maximum 1GB capacity.

According to this site

your camera does not support the SDHC cards.
