About powering the drive off:
in gnome shell (standard install), I have on right-clic the ability to safely
remove the drive.
I tested udisks --detach /dev/sdx, which had the exact same effect.
It works, but it immediately starts again. Not mounting, but still getting
powered on again.
My goal is to keep it off.
The other thing is that I get a message telling me that the drive is in use
every time I try to unmount. But the only thing that's on is Nautilus.
Compared to my netinstall: udisks --detach has the intended effect, but I
have yet to associate the right-clic to Thunar.
