Query: Never worked in my iPAQ

After waiting several weeks for the 128MB SD card to arrive, I finally got it. Gleefully I inserted it into my Compaq iPAQ's SD slot and -- pffftttttttttt. Nothing. Nothing at all. I got an error dialog box saying the card was unrecognizable... Didn't even allow me to format it or anything...I have had no problems with my SanDisk 64MB SD card.
