8GB SDHC Problem

[stroths]

It looks like your file allocation table is corrupt, but there should be a 2nd copy (providing its not bad too). Run checkdisk on your PC and see if it can fix it and let it check for bad sectors as well.

If the data you have is not backed up somewhere and you really need it, you might try some recovery programs on your PC like Get My Data Back.

I know that hindsight is always 20/20, but always keep a good backup. I have so much customization (Sashami, mortscripts, cabs, etc) on my 8gb that it would be a real pain to start over. Any time I make any significant changes, I backup the card to a my computer.
