Thanks! Glad you liked the report.
I took the bad memory card to Best Buy, and they said there was nothing they could do, but they could send it out to another place that could definitely recover them for a LOT of $$$$. Alternately, he suggested that I go to SanDisk's website, where they had a link to some recovery software they recommend, RescuePro by LC Technologies. The software was able to recognize the card as a drive, and found 98% of the stuff that was on the card (including hundreds of pictures I'd previously deleted, but, oh well, the ones I wanted were in there with the rest.) I first ran the Demo version, to make sure it could actually find the pictures, but the Demo version doesn't allow you to save what it finds. Since it found them, I went ahead & spent the $40 to buy the software, and recovered almost all of my pictures. One quirk I found is that it retrieved video as multiple snapshots, so it looked like there were a TON more pictures that I'd really taken.
If you need any help with the software, let me know. But LC Technologies' technical help were really responsive.
