    If the ext4 partition is actively used by the currently running operating system, then you will not be able to unmount it. Instead boot from live media, such as the Ubuntu Live CD, or [GParted Live CD](http://gparted.org/livecd.php) and perform your partitioning from there. – Curtis Gedak Aug 01 '15 at 22:50

I have not had this problem but try just unplugging if it is not doing any work.

sudo umount /mnt/share
