but it isn't nonsense.  Welcome to the world of Windowz, where one
'ejects' a USB stick and then gets a pop-up saying something about
safe to remove the hardware now.

Maybe there's a command to unmount / sync / whatever a USB stick but
I've always used Windows Explorer and the only option for what to do
before unplugging a USB stick is to eject it.

Well, no..  I used to have bash scripts that worked on SunOS and then
later Red Hat as well as cygwin.  I've gotten used to things Just
Working across platforms, so this failing is a bit of a surprise.

know better than you and doing whatever regardless of what you want.

Me either.  I'm not going to worry about it - other than reinstall
Debian on my laptop from a USB stick written on a Debian machine :)
