Get a card reader. Connect the card to your computer. Even if it can't read it, you can use Disk Management (Control Panel/Administrative Tools/Computer Management) to delete all partitions on the card, create a partition (or more than one, however you run your phone), then put the card back into the phone and format it.
Let me know if that works.
