Writing to an USB stick on Fedora 19

What's the correct way to write an image to a USB stick? I don't write
to it while any file systems are mounted. Mounting happens
automatically when I plug in the stick, and if I click "Eject" in the
GNOME notification, the /dev/sdb block device assigned to the stick is
still present, but dead—the open system call fails with ENOMEDIUM.
I've got a fairly default Fedora 19 installation, running GNOME in
Classic Mode, still running the 3.11.6-201.fc19.x86_64 kernel.
(Right now, I overwrite the start of the stick with zeros while the
system is mounted, sync, unplug, and the plug it in again, for the
actual write operation, but that can't be the right thing to do.)
