Sandisk CF Card Problem - Can read in USB Card Reader but not in Camera

[anthony.phua]

Has anyone encountered such a problem? My 4 year old 1 GB Sandisk Extreme has stopped working in my camera. The camera don't even detect the card anymore. I tried on two cameras and the result is the same.

I tried using my USB Card Reader. The card can be deleted. I formatted the card on my PC and put back into the camera but to no avail.

Any recommended solutions for me to try?

Thanks in advance.
