You could do
sync -f $StickTarget;sync -f $StickTarget
umount $StickTarget
to only sync the USB stick. I'm not sure your really need the second
sync. IIRC you need to "sync;sync" before shutdown in case there's
something being written to a system directory behind the scenes. In
your situation with a specific stick, I don't think that's the case.
