|Ejecter in action|
The long way round goes Start > System Tools > Disk Utility
Click on the drive, then click on Unmount, then click on Safely remove.
sudo apt-get install ejecter
You need to run it (it might autorun after I reboot or something) I need to check how to run programs at startup again...
Now, I am going to research this further - but Ejecter only unmounts the drive. It does not power it down as well. I am not sure if both are absolutely necessary, but I have lost data before by just unplugging a flash drive - so I will investigate.
