I have just discovered that if you use the 'Disk Utility' program (found in System -> Administration) to unmount the USB drives, then no errors are generated. After unmounting, the icons for the drives then appear as unmounted in nautilus.
You can then physically remove the USB device / media player and everything is fine, and the drive icons then disappear from nautilus.
You don't get the "Writing data to <drive>" pop up.
So the Disk Utility is doing the unmount in a different way to Nautilus?
(the above was tried with quirks's software mod installed)
