It seems repetitive even to myself asking this but I've searched this forum and have not been able to fix my issue. I had created one extended partition and installed my UBUNTU 14.04 on it.
Now I have 440 GB available so have recently created two new primary partitions on the free space. But when I click them to mount and access them from the "Places" menu (I have installed Ubuntu-mate) the only thing there I would have is a window opened and I can not create anything on it.
I figured it may have been mounted as root and I have not a single clue how to change it to my username. Could you please help me?
