 ... snip good stuff...

You should be checking something!

In the mount point you can place a file "USB-XYZ-DRIVE-NOT-MOUNTED"
and if that file exists do something sane.

On the USB device you should have a volume name or magic file
that labels the drive.  If the file and or label is absent
do something sane.

Since USB is so flexible and dynamic some sanity checking is needed
if you automate reading and writing.

I am not thinking security, just simple sanity checks.
Use a Makefile or some other automating script trick, you can
have a make dependency on the magic files.
