Since three months I am waiting and searching for a solution to mount a USB stick again.

I am using Ubuntu 11.10 32bit and 64bit Dell machines and I could not really find a useful answer what exactly I need to do being able to mount a USB Stick.

Unable to mount [VolumeName] Not authorized

Can you please point me in the right direction what I need to do/change/adjust being able to mount a USB device again?

This happened to me when I added a nopasswd user. When I removed that user the problem went away. –  hbdgaf Apr 8 '12 at 21:31
Can you mount it as root (sudo mount /dev/disk/by-label/whatever /media/wherever)? –  ohno Apr 8 '12 at 22:18

I think this could be the answer here:


It says: "If your usb device doesn't appear on your desktop, you should check that your user has the correct privileges. Go to System->Administration->User and Groups, choose the user, click on "Properties", then go to the "User Privileges" tab. You should have the "Access external storage devices automatically" option checked."

If your USB stick is formatted ntfs make sure you have the NTFS Fuse programs installed.

sudo apt-get update && sudo apt-get upgrade && sudo apt-get install ntfs-3g ntfsprogs;
