Memory Card Problem

[call.milo]

I have two 128 MB memory cards for my FUJIFILM FinePix A340. One of them works fine, and one of them doesn't work at all. When I put the card that doesn't work in the camera, it reads and says "Card Error". I cleaned it and it still doesn't work. Does anyone know why it's not working or know what I'm doing wrong? Thanks.
