For this kind of symlink the problem is the missing DOS SYSTEM file
attribute. This attribute is used to recognize symlinks in the first
place. Only files with the SYSTEM bit are opened and their content
examined if they are symlinks.
I don't know anything about your external drive, so I don't know where
the SYSTEM bit was lost. In fact, rsync should just have tried to create
symlinks either way, so I assume the system bit has gone lost due to
some unrelated operation.

find the files by their !<symlink> header and set the DOS SYSTEM
attribute. That fixes it.
