Brand new sd card has been placed inside the camera, its still saying that the card is full when nothing is on it.

Most of the time, SD cards are empty but it says that it is full. This happens because of the incorrect file system issue. So, format the card and check again. On formating, the SD card will show no data.

Format the new sd card in the camera.

Format the SD card make sure the camera is set to place the new files on the SD card and not go to the internal memory. What I fully expect is the camera has defaulted to using the internal memory which is now full of files/pictures and needs to be set back to SD card. To get the pictures from the internal memory to your computer you need to load the pictures one by one from the internal memory to the SD card. Then take them from the SD card ether to a card reader to the computer or download them from the camera to the computer.

format it and run avg on it

Your camera probbaly does not use SDHC... just SD...
Find an SD memory card, it will work. The 4GB card says "SDHC", not "SD".

Please post the brand and model or whatever you can ... which camera?

Some of the older cameras will not take the bigger cards. You can use the bigger card with your computer to store your photos.

The SD card may have to be reformated. You should do this in the camera you want to use the SD card with. Do not format the card with your computer.

In you manual or on the menu of your camera there is a "Format" procedure. follow that and your camera will work again (REMEMBER) if you have images on the SD card down load them before you format the card.

Once you down load the images from your camera you should reformat the card to clear it in order to shoot more images.

Here is what you do. You take out the tiny Memory card and blow on and it, and blow i the inside. Then insert memory card. Take out batteries and put the batteries back in. Push Power and Start Recording., Chaow

this camera is actually really compatible with the 2gb sd card, anything higher will give you that message. since you have the right kind but still won't work - 2 possibilities:

camera memory ready issue > repair necessary
defective card> try another one

You will have to check this out on the manual. There is a full manual on the software CD
