When I put the memory card in and turn on the camera, it keeps saying memory card error.

Normally, you can only insert an SD card one way. Try a different SD card or check to see if the SD card you're using has the "write protect" switch on. If that's not the issue try formatting the card in your PC and then format it in the camera.

Keep in mind tha compabilitie memory card for this camera. Try formating your memory card.

Error 99 is a catch basin for a number of problems I'm going to assume that because this is a new camera that you didn't format the memory card. Formatting a memory card makes it function perfectly with the camera it's being used in. Also after pictures have been downloaded to the computer you need to format the memory card, cleaning all the old pictures off the card and giving you a fresh clean medium to use to put new pictures on. You will see also that there is this little handy garbage can icon and this is or should be used only when you find you need more space on the card when you are shooting and not the way to clear the card. The memory card should always be formatted in the camera.

make shore the memory card is out of the camera and reformatte the interal memory and reset the camera ,turn it off and put the memory card back in it should work now.

Try one of these two fixes, if they dont work for you follow the link below for further troubleshooting.

Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.
Fix #2: If the camera's batteries ran down completely while the its lens was still open, the camera may show a lens error or not start properly when new batteries are installed. Remove the memory card and keep it removed, then install the new batteries. When you turn the camera on with the card removed it may come back to life, as this triggers a reset in some cameras. Error E30 (for older Canon's) means that you don't have a memory card installed, so turn it off, slip in the SD card and turn it on one last time

Your memory card needs a permanent home. Trading it between cameras is corrupting it. If there are pics on it, use a card reader to download them. Then choose a camera and format the card in that camera.

Take out memory card from camera, turn it On and check does it show format error?
If yes, press Home, Memory option and format internal memory.
If camera does not show format error then put back memory card in and press Home, Memory card option and format it.
This will delete all files/ data and will refresh memory card, take some pictures and check.
If after formatting, still format error exist, put new memory card.

Guys you have to have the camera format the SD card itself for best results and compatibility.

not reading memory card; keeps saying reinsert memory card, diplays error C 1

Hi,
Try this:

- Turn off your camera and take the batteries out
- Then take the memory card out
- Leave the batteries out for around 10 minutes
- Then put the memory card back in
- Then put the batteries back in and turn the camera on
- Try to see the pic/watch movie again

If this didn't work, check the memory card with a card reader...if it still gives an error then the card might have malfunctioned or needs a reformat.

Good luck!
