Ubuntu 11.04 “The destination is read-only” – thumbdrive – GNOME error

I have Ubuntu 12.04.
My problem is, I can't get write access to any USB device, like thumbdrive, SD card or digital camera using GNOME 3.4.1.

Both FAT32 and NTFS filesystems won't work.

From terminal I can create files without any problems…

But when I do this same from GNOME file explorer: "The destination is read-only":

And /media:

root@alan-OEM:/media# ls -l
total 12
drwx------ 26 alan alan 8192 sty  1  1970 CC2A-FA36

("alan" is my account.)
It looks like like I have read-write-execute.

So from terminal:

alan@alan-OEM:/media/CC2A-FA36$ mkdir zzz
alan@alan-OEM:/media/CC2A-FA36$ mkdir zzzz


drwx------  2 alan alan     4096 lip  1 22:49 zzz
drwx------  2 alan alan     4096 lip  1 22:49 zzzz

Work great… but from GNOME I can't….
It's making me crazy…
