"No medium found" trying to overwrite USB media ... [solved]

Following the guidelines in the Wiki 'USB Installation Media', I tried to transfer the latest archlinux iso to a USB drive to function as a rescue disk:

sudo dd bs=4M if=archlinux-2012.11.01-dual.iso of=/dev/sdc

But when I enter this command, I get the following error message:

dd: opening ‘/dev/sdc’: No medium found

The Gnome Disks-utility shows that the USB drive is indeed located at /dev/sdc. It is not mounted.

I have tried this with two different USB drives. What am I doing wrong here?

Okay, I may have fixed this myself... I first unmounted the drive with Nautilus, but when I use umount to unmount the drive, the dd-command works...

Don't forget to mark the topic as solved (by editing the first post) so that other people (including yourself sometimes) may find useful.

I ran into this yesterday. I think that nautilus uses 'eject' or some other magic that messes with your device file.
