Sd card cannot be read & internal memory of camera cannot be read

the camera has internal memory and also will have the option for external memory. If you have a sd memory card in the camera you can backup the internal memory to the sd card.
Then you can remove the sd card and put in a new sd card and you now have an sd card with your precious photo memory's copied from the camera internal memory. You may have a camera that allows two sd cards one for the photos and one to back up the photos. If you had your camera stolen or lost you would lose all the photos on the camera but with a backup sd card you still have the photo files. Also a p.c with a card reader device could read the files on the sd card and you could copy them into a cloud storage on the net or onto a network storage device or onto a usb portable drive with 2 terrabyte capacity .

it seems that your camera is still on internal memory, if your camera was off when you inserted your sd card, ( it needs to be off when inserting it) it should automatically switch over to the sd card.
I'm not sure with yours, but with mine( I have an older version ) I can go into settings & switch it back & forth from internal memory & sd card.

here is a link to an extended user guide for your camera.

4GB "SD" cards are almost always actually SDHC (high capacity) cards. SD and SDHC cards fit the same slots, but they are slightly different electrically. Many cameras won't work with SDHC cards. SDHC is not backwards compatible.

So your camera is not able to use the 4GB card, and is ignoring it and using internal memory only. That memory is tiny and won't hold many pictures, and when it is full, the camera cannot work at all. You need to delete the pics in the internal memory and get a memory card your camera can understand (2GB or less).

Your camera is only supporting: SD/MMC up to 1 Gigabyte

The card that you currently have might be high speed. All should be sorted if you change the SD card to the supported MMC SD card up to 1G. There is a lever on the SD card this one might need to be changed.

The card that you currently have might be faulty. Please try another card.
You might also need to switch the camera over to saving pictures directly onto the SD card.1: Menu, Cam settings, Chose AUTO or SD card option Press OK

Note: If the SD card isn't in the camera or is unreadable the camera will automatically go back to saving you taken pictures on the internal memory.

Note: If the SD card isn't in the camera or is unreadable the camera will automatically go back to saving you taken pictures on the internal memory.

If you experience problems:
The lever on your SD card might be turned the wrong way so the SD card is reading protective.
Please turn the lever and try again.

The SD card might not be supported by the model: Your camera Memory card support is SD/MMC up to 2 Gigabyte and SDHC up to 8 Gigabyte

The SD card might not be faulty, try another card, since the camera could give you a message like the one you're experiencing.
Try with a different SD card that is supported by the camera.

Once you have set the settings to save onto the SD card directly you might like to transferre your existing pictures from the internal memory onto the SD card:

You need to delete stuff on the memory card or put a empty memory card in there

If I remember correctly, when you insert an SD card, it "hides" the camera's internal memory. There should be an camera option for copying the files from the internal memory onto the inserted SD card. If not, you could try connecting the camera to your computer with the SD card removed, in order to access the files in the internal memory.
