When I plug in my USB Drive, I get an icon on the desktop which allows
me to mount and unmount the first partition (the Windoze one) of the
drive.  There is no similar icon/option for the second partition
(Linux), so I don't know of any way to mount/unmount it other than by
using the command line.  I can do command line, but if someone else
(non-technical) is using the system, I don't want them anywhere near the
command line.  Other than my convenience, that's what this whole
discussion is about.

Yes.  I just learned about that working on repartitioning my drive.
