Other than shutting down or pulling the cord out.
May not be a kernel bug, didn't know otherwise..

Test case:
boot up, log in
attach a usb 3 hdd ( one without externel power
The option to "Safely Remove" will be available in nautilus & unity launcher icon, click on it

What happens:
Drive is unmounted, momentarily powered off & then repowered on ( takes less than a sec.
What should happen:
drive should be powered off & stay off until re-attached

If one connects the drive to a usb 2 port then it will power down

To further confuse -
If one boots up with the device connected or after connecting after login then log out/in there is no longer a Safely remove option, only mount or unmount

At no time does udisksctl power-off -b /path/to actually work, it acts like first scenario, quickly powered off then right back on.

Whether useful don't know-
