Unfortunately, the device system:/media/sdf1 (/dev/sdf1) named '4.0G Removable Media' and currently mounted at /media/disk could not be unmounted. 
Unmounting failed due to the following error:
Method "Unmount" with signature "as" on interface "org.freedesktop.Hal.Device.Volume" doesn't exist 
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.

Cannot stat /media/disk: No such file or directory
Cannot stat /media/disk: No such file or directory
Cannot stat /media/disk: No such file or directory

The KDE mediamanager is not running.
