Spam.
But I thought I'd add a couple actual tips.
Scenario 1:
Files are on card but not viewable and can't be copied (some filesystem corruption).
dd the whole SD card to a file and then mount that file (I used this method just a few days ago and recovered 100% of the photos)
Scenario 2:
Files have been deleted
Use photorec to recover the files
This method is hit and miss and I usually can't recover all the files
Scenario 3:
Partition(s) have been deleted
Use testdisk to recover the entire partitions (write a new partition table). Again hit and miss.
I recommend the GParted LiveCD. It has photorec + testdisk, of course dd, and well GParted installed too - good recovery disc to have around.
