Using previous posts, I used the following command in fedora21 terminal to remove the external drive safely:# umount full_path_to_external_driveWhen I checked with the command df -k, the external looked removed, but  its icon was seen in the desktop. If I clicked that icon, the external drive again got mounted. How can I remove the external drive safely in fedora21?
