Help - corrupt Compact Flash card!

Dear all;

I have a problem, and I hope it's not a BIG one.
During the past weekend, I have taken more than 200 photos
on a 512Mb Compact Flash card.
While taking the last picture, the camera suddenly displayed "Card error" and then shut down.
Since then, I can no longer access the card!
Not even on my computer, and not even while using a seperate card reader.

Some observations:
- The card worked perfectly during the entire weekend,
until I shot that last photo where the error was displayed.
- I have an old camera. Is it possible that these are not compatible with big CF cards of 512Mb and more?
- BEFORE I started using the card this weekend, I had already noticed that, when reading it with a card reader,
Windows Explorer shows not one, but TWO removable media,
of which one is empty.
- I had reformatted the card on my computer before using it this weekend. I have heard that this is not good, and that it's always better to reformat CF cards on your camera instead. Maybe this is a possible cause?
- I have tried Pantera Soft's Flash File Recovery.
The problem is that this tool only seems to see the empty partition on the flash card, not the one on which the photos are stored.
- I THINK that maybe the FAT32 file system is corrupt.

Conclusion: Does anyone have experience with recovering data from corrupt CF cards?
Apart from the tool I used, have you had any good experience with another tool for restoring data from a corrupt CF card?

Many thanks in advance!
I hope I haven't lost more than 200 photos.

If the memory card is not recognized in the PC or it is impossible to access the data on it, the controller on the card is damaged. There is only one way to get the data back, unsolder memory chips and directly access their raw data with a programable chip reader. Software can't help, that is a physical damage!
