My Sandisk 256m SD card -- which I have been using without problems for several years -- stopped working today. When I insert it, it just asks if I want to format the card. Does the same on my 650, unfortunately.

I am traveling (of course) so can't do anything with my card reader. Any ideas? Any hope of fixing it or at least restoring my data? I searched, but other threads seemed device specific. This definitely appears to be the card itself.

What the heck could've happened?? Was fine this am, took it out and put in my 1 gig to listen to music, and when I reinserted it, this. Frustrating. Help!

Thanks.
