I have an HP Compaq 6910p that I upgrade into 11.10 a month ago. It works nicely with only one disability so far. I can't change anything in my external hard disk. It is connected through a USB 3.0.

I can read it in my computer, but in the properties it said that the permission is read-only, and I can't change it. So I can only copy files from it. It sucks because I need to do a lot of things with it. Help me please...

I had a similar problem...

I had ntfs-3g installed. In my case Ubuntu removed it? of course i am assuming you have an NTFS EXT-HDD

please copy/paste this into gnome-terminal to install ntfs-3g:

 sudo apt-get install ntfs-3g

Or via the Ubuntu Software Center. Just search for ntfs-3g

Try using Nautilus as root: go to terminal and type "sudo nautilus."

Change the permission properties from there.
