Is it possible to retrieve the data from a corrupt SD card?

….I assume it’s corrupt.
I have no idea, actually.

It’s a 2GB SD card.
It worked fine an hour ago, then I tried to put it back in my laptop, and I couldn’t access the files. Computer: “REFORMAT, NOW”. Me: <dies>

I tried it in my camera again with the same results.

They both recognize it, but I have no desire to reformat the card to please them.
There are some pretty important pictures on there..

Is this a lost cause?
