Same issue here but comes and goes. Yesterday I could not write any of
my usb sticks. The funny thing is that I was able to write in them
through command line.
Today the issue is gone. I've experienced this problem about 3 or 4
times in 3 months time.

Nautilus says the USB stick is read only when it is not
Status in Nautilus:
Status in nautilus package in Ubuntu:
First time I use an USB drive since I updated to 12.04 and I found a
really annoying bug on Nautilus. Nautilus claims that the destination
drive is read-only when in fact it is not.
How to reproduce:
1. Connect a USB stick drive to your competer.
2. The USB will appear in the desktop.
3. Open two Nautilus windows one in your home folder, other in the USB stick
4. Select any file from your home folder (small enough to fit the free space
in the USB drive)
5. Drag the file and drop it in the USB drive window.
-- Nautilus will say that it cannot copy the file because the
destination is read ony --
If you try the copy the same file with the terminal you will see that
the file is copied without problem, other programs like gedit or
LibreOffice can write in the usb stick drive just fine.
It is not a problem with the USB stick, as shown here:

The permisions on the removable drive are set correctly:

There is enough free space in the drive:

But nautilus just dennies to copy the file claming that the
destination is read only, when it is not.
I tested it with two different USB sticks in two different computers
running Ubuntu 12.04 and the same result.
