It's not very helpful but I have seen something similar in a friend's 
128Mb Smartmedia card/USB reader/RedHat 7.3.

He mounted and unmounted the card from linux and saw a small number of 
files (3 images). Took more photos on the camera in addition to the 
three images, and from another linux box it was possible to view the 
whole set of images. From the original linux box only three images were 
visible.

We messed about with an entry in /etc/fstab as updfstab was unable to 
run on that system. We commented the line:

/dev/sda1              /mnt/smartMedia         auto    owner

Then we mounted by hand as root, and the linux box was able to see all 
the images.

I think there is something strange going on in the auto filesystem 
detection. If the VFAT / FAT16 / FAT32 filesystems are in some way 
similar when empty or with few files, there seems to be problems. Also 
do some DOS filesystems have more than one copy of the FAT? Are we 
looking at the wrong one or an old one??

Did you have a fstab entry with auto in it?

Finally, I also have some trouble with a 32Mb Smartmedia card - when I 
have erased all the pics from it (leaving only a filesystem and two 
nested directories), it sometimes fails to mount. Since this is so 
patchy I'm thinking it may be the card that is faulty.
