Funnily, my newly vfat-formatted USB stick is automatically mounted when I plug it in, nautilus sees it, I can access it, I can see the permissions in the nautilus right click dialog (755), I can create and delete files from command line:
I can even move files (with Del key) into trash from within nautilus.
But when I try to create a new directory,a new file, or copy a file to that stick using nautilus in Arch linux, I just get the error message (German):
Fehler beim Kopieren nach »Datenträger 4,0 GB«. Das Ziel ist schreibgeschützt
Which means: **Error copying to »Storage device 4,0 GB - Target is read-only«
I don't get it. It can't be on OS layer. I can touch, delete, renamy, copy anything on the command line. It must be something GNOME restricts. Is it necessary to be in a group in Arch/GNOME to write to USB devices? And why can I delete files (Move to trash and delete is possible from within nautilus!) I am in the following groups:
