I have a 160GB external USB drive with two partitions.  On OpenSUSE
10.3 and Kubuntu 8.04 it gets mounted as /media/disk and
/media/disk-1.  I usually interact with it from the GUI.  Each distro
behaves a bit differently.

OpenSUSE
When I unmount one of them the file system is closed but a dialog pops
up that it cannot eject the device.  But that partition is not mounted
anymore.  Then when I unmount the other partition both icons go away
and I unplug it.

Kubuntu
When I unmount one of them the file system is closed and there is no
dialog.  The icon remains.  Then I unmount the other and it's icon
still remains.  If I click the icon to get the menu, the "Mount"
option is visible, indicating to me that it is not mounted.  When I
unplug the drive, the icons disappear.

Admittedly I have not looked at mtab during these steps to see when
"true" unmounting has occurred.  I am trusting the icons and menus to
tell me it's safe to unplug.  So maybe my experience doesn't help you
much.  I have not had disk corruption following the above sequences.

Maybe the file system really is unmounted, depending on how Clonezilla
handles the unmount event and subsequent configuration state updates.
