Thanks, Adalbert. The messages that I get are:

"rsync warning: some files vanished before they could be transferred
(code 24) at main.c(1040) [sender=3.0.3]"

This happens with accented filenames.

After having removed all accents, I do not get any error message.

Still the reported problem occurs: rsync needs to copy all files after
umounting and subsequent mounting of my pen. This is the behavior that
I am wanting to control: rsync should copy only modified files. Before
unmounting my pen, rsyinc copies only modified files; but after having
umounted my pen and mounted it again, rsync copies all files. Any
ideas?
