If you don't need real-time synchronization, and don't handle gigabyes of 
data, maybe aliasing umount could be an option (this is kind of hackish, 
of course):

-------------------------------------------------------------------
#!/bin/bash

# assuming your removabile device is mounted under /mnt/external
# assuming umount is called by mountpoint and not by device name

MOUNTPOINT="/mnt/external"

if [ "$1" == "$MOUNTPOINT" ]; then

  echo "Synchronizing..."

  # put here whatever command you want to use for synching, eg rsync

  ....

fi

/bin/umount $1
exit $?
-------------------------------------------------------------------


Save tha above script into a file named "umount", and put it in your path 
so that it is found before the real /bin/umount. Or you can do the same 
with a shell alias.
Great care must be taken when modifying or aliasing important system 
commands, since you kind of break the integrity of your system.
