unmounting a evice
 

I recently installed the gnome-disk-utililty which I know from ubuntu. With this prog I wanted to unmount the usb stick, but I receive the error code - not authorized to perform operatio ( udisk-error-quark,4). What can I do to unmout the device?
The mountbox in Antix doesn t work properly, cause you can t switch to the devices for unmounting

Use the unmounter icon in the task bar on the bottom left

I ve overseen that.
