memory stick error

Help would be appreciated.
I have two different memory sticks
 Kingston Technology Company Inc.
 Silicon Integrated Systems Corp. Super Flash 1GB / GXT 64MB Flash Drive

I am running ubuntu 14.04 LTS on my two computers.
Both memory sticks used to work on both computers but now they only work on one.
On my laptop now, both memory sticks give the error:-

Invalid uri:'/media/george/"Name of Stick"'given,exiting
No':'in the uri

Neither my user name nor password contains contains any invalid character.

Using 'mesg':-
