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":

Error

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...

What do you mean by from gnome i can't. What is gnome? Do you mean Nautilus? –  criziot Jul 1 '12 at 23:30
    
Can you create both files and directories from the terminal, and neither from Nautilus? I see the dmask specified but no fmask. But I have no idea why you can do something from terminal but not nautilus, unless you are root in one and yourself in the other (I do see some prompts show you as root). –  Marty Fried Jul 2 '12 at 2:13

I just ran into this issue with 14.04! All I wanted to do was copy a single file onto my thumbdrive. Luckily this question mentioned that it works in the terminal so I that's what I ended up doing.

Apparently it's still an open bug 😒: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1021375
