Unfortunately, the device system:/media/sdb1 (/dev/sdb1) named '80G Media' and currently mounted at /media/disk could not be unmounted. 
Unmounting failed due to the following error:
Device is Busy:
Moreover, programs still using the device have been detected. They are listed below. You have to close them or change their working directory before attempting to unmount the device again.
                     USER        PID ACCESS COMMAND
/media/disk:         tdn       15021 f.... dbus-launch
                     tdn       15022 f.... dbus-daemon


These processes are:
tdn      15021  0.0  0.0   2916   328 ?        S    20:54   0:00 dbus-launch --autolaunch 7b4bc6d203dd0e31045f8e0047833f00 --binary-syntax --close-stderr
tdn      15022  0.0  0.0   2776   944 ?        Ss   20:54   0:00 /usr/bin/dbus-daemon --fork --print-pid 6 --print-address 8 --session


Should I just kill them?
