daemon is inhibited (Dreamlinux)

Today I found some problems on my Dreamlinux.

one of which is my external hard drive can not be unmounted.

after I searched on Google, I get a solution to this problem.

open your terminal and type :

loner_182 @ dream: ~ $ ls-l / media 

Note the mount points (/) partition here is only accessible by root.
Then we must add the user permision loner_182 with the following command :
loner_182 @ dream:~$ sudo chown -R loner /media/Data

You will see another error that appears. but don´t panic, because here I am going to mount the media is not the data. so, type the command was repeated without the use of / Data
Such loner_182 @ dream: ~ $ sudo chown-R Loner / media /

if no error appears it means you're successful and now you have an external hard drive can be mounted.
Good luck.
