[insomniac]

This has happened to me twice, I had to plug in my phone to my laptop as mass storage, go to computer, click on properties, click on tool, then click check disk, click both scan dissk for file errors and bad sectors, and have no issues since, it fixed it and only took a few mins for a 16 gig card, but I did loose about 3 or 4 cabs i had saved on the card, but that wasnt that big of a deal, lost nothing else.
