I have this problem too. All the other methods to eject/unmount the devece are succesful (including sudo eject /dev/sdc).
When clicking on "Safely remove drive" from nautilus I get:
Unable to stop 120 GB Hard Disk
Error detaching: helper exited with exit code 1: sense buffer empty
Error SYNCHRONIZE CACHE for /dev/sdc: Successsense buffer empty
Error STOP UNIT for /dev/sdc: No such file or directory
