My understanding, and it could be completely wrong, is that Linux
distributions usually use something like amd(8) (the automount daemon)
to manage removable devices.  They automount automagically when
inserted, and unmount when they haven't been used for a while, so if
you forget about them and pull them out they are usually not mounted
and don't cause problems.

You might try setting up amd(8) to see if that makes things more robust.
