why does this rsync commands copy again the same files?

Indeed! Thanks. Here are the outputs of fstat on two copies of the
same file, just rsync-ed from the ext4 folder to the vfat ext drive:

[marco at avalon LACIE]$ stat  --format "%y" /home/z/photo/2011/20110719/P1110546.JPG

OK, thanks you got it exactly right!!! But, now what? Is there any way
to keep the drive vfat AND end this problem, without losing file
modification time? I'd really like to keep the vfat simply because some of
those drives are not mine (*)
