You can change File/Fodder permissions by Opening up a terminal by pressing Ctrl+Alt+T and typing in

This command will change all sub directory’s and files to read and right to every one.

sudo chmod ugo+wrx /media/external -Rf 

Or you can run sudo nautilus in Terminal this will run nautilus with full rights so you won't have any permission errors when copying files and fodders to an external media.

If you want to copy your important data open the file browser (nautilus) as root :

Open a terminal (Ctrl+Alt+T) and execute :

sudo apt-get install gksudo

When the installation is done :

gksudo dbus-launch nautilus

Copy your files ...
