Hmm...
When you delete files on FAT formatted media, I thought what happened
is that you overwrite the information stored in the FAT about which
disk blocks are in use. Hence if there are no files (and no
directories), no disk blocks are marked as used and you would have
nothing to defrag.
I may be wrong... :-)
I have encountered a situation where I used a computer to delete files
from the memory card and the camera wouldn't read the card after.
I was able to format the card in camera and continue to use it.
