I did not personally have a usb 3 external hdd prior to 14.04
There are quite a number of bug reports concerning the 'auto remounting' 
of usb hdd drives going back quite some time. One example -

The points here are -
Only happens with usb 3 hdd's
Only happens with usb 3 when attached to a usb 3 port
The option's on these drives aren't consistent -
   Safely Remove only when attaching after login (- this option fails 
it's purpose
   Unmount only when booting up with drive attached or after a log out 
in with drive attached (- this option works
And there is no way to power of the device when attached to a usb 3 port 
(other than going to suspend), windows & mac's can.

  Usb 3 hdd drives cannot be powered off in any manner

Status in linux package in Ubuntu:

Bug description:
  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 external power) to a usb 3 port
  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 re-powered 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 connecting after login then doing 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.
