There are many fake compact flash cards out there. They read the correct capacity but are often much smaller. I bought a fake sandisk 4gb. PCMCIA does not read it. PC reads and formats it, but random errors show up. Would not work in my A4000 unless it was the only drive. then it would show read write errors. Bought a genuine Sandisk 4gb from a bricks and mortar store and NO PROBLEMS on PCMCIA or IDE adaptor.
