Comment 12 for bug 445810

I understand the distinction between unmount, eject and safe-remove, but the issue isn't that a drive "still" appears in usb-creator after being removed. (Note that I'm only talking about the safe-remove action, not physical disconnection from the USB bus.)

What happens is that on startup, usb-creator does some sort of udev/dbus-fu that causes all plugged-in USB drive partitions to reappear (if they aren't mounted already) on the desktop---icons, automount, everything. The drive/partition that had been previously unmounted, or safe-removed, is suddenly present again as if it had been reconnected and redetected, in addition to being listed in usb-creator's list of devices.
