Perhaps in days gone by: my OS prior to Wheezy -- Fedora 12 --
was like that. Anything USB had to be mounted/unmounted manually.
What a pain.  And if you unplugged without unmounting . . .  Yes, things
could break. But with Wheezy which I've been using for 3+ years have
had no problems with just plug/unplug. The only precaution is to check
the drive activity light isn't flickering.

Of course, my install of Wheezy is very custom and minimal: for the GUI
just a window manager, Openbox.  And I custom wrote my own udev rules
for handling USB devices -- thumb drives, cell phones, eBook reader,
etc. But a regular desktop should be set up to do the same thing,
safely.

If the OP's GNOME Shell is not doing this, but other desktops are, then
GNOME might be the problem.
