On my Samsung Digimax S800 when I put a sd card in, it says to check sd card. What do I do about it?

When the card worked before, check if you did not switch the lock switch down. And check all contacts on the card and in the camera. They should be clean and shiny.
When you recently bought a new card you could have bough a SDHC card and these won't work in your S800.
The S800 only accepts MMC and SD cards, The SDHC and SDXC cards won't work.
A few years ago you still could buy 4 Gbyte SD cards. Now even most 1 Gbyte and 2 Gbyte cards are already SDHC. SDHC was introduced at least 7 or 8 years ago, so all new devices accept SDHC. The SDXC was introduced at least 4 years ago, so in a couple of years, you perhaps only can buy these cards?

What type and size memory card? The S800 uses MMC and SD cards. It will not work with SDHC cards even though they'll fit into the slot.

Probably, especially if your card is a 4GB or larger SDHC card, then it's definitely the wrong card. The older Digimax S800 camera can only use standard SD cards (2GB or less). Fortunately, these are very inexpensive these days, and may be found on Amazon if your local store no longer carries them.For others reading this experiencing similar problems, please see this article.

Hello Eilee,

Remove the memory card from your camera and check for a tiny switch on it. Make sure it is not set to "Lock". If it is, then switch it back to unlock.

However, if your memory card does not have the "Lock Feature" it could mean that your card is already malfunctioning. Try reformatting it first before buying a new one.

Note: You will loose ALL data from your SD card once you format it.

You can rate my answer if you appreciate it.
Thanks!

SD cards max out at 2GB. Higher capacity cards are actually SDHC cards (the HC stands for High Capacity).

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

The Samsung Digimax S800 digital camera is only guaranteed up to 1gb SD cards, meaning you might be able to get away with something larger, but it was only manufactured for up to 1gb. Hope this helps.

remove the sd card and insert it firmly if not workin service the sd card slot

There is a small tab (like a very small hole with a sliding piece of plastic) on the corner of the memory card. Slide it to unlock it :)
