Comment 16 for bug 1239087

Thank you for your commits, David!

I installed all build-dependencies on my Ubuntu 14.04 system with 'apt-get install build-dep', did a 'git clone git://anongit.freedesktop.org/udisks', did './autogen.sh', did 'make', did 'sudo checkinstall make install', verified that I have udisks 2.1.3 installed with 'apt-cache policy', did 'mv /usr/local/share/polkit-1/actions/org.freedesktop.udisks2.policy /usr/share/polkit-1/actions/' and rebooted my machine.

Please note: automount is disabled.
What I get after reboot?

1. for USB-HDDs (both drives have EXT4 and NTFS partitions)
1.1. Seagate - 'Safely remove drive' option in Nautilus spinned-down it, gnome-disks spinned-down it after click on 'Power off the drive'. The 'udisksctl power-off -b /dev/sdX' works too.
If I enable automount, the 'Safely remove drive'/'Power off the drive' spins-down my drive. It's very good!

1.2. WD - 'Safely remove drive' option in Nautilus spinned-down it, gnome-disks 'Power off the drive' and 'udisksctl power-off -b /dev/sdX' works too.
But there is a little difference - if I enable automount the 'Safely remove drive'/'Power off the drive' does not spin-down the disk (disk plates rotating, but device is removed from system), I reopen the bug because of this.

2. for USB-flashes
There is no 'Safely remove drive' option in Nautilus for my USB-flashes. After 'Eject' the parent device remains in system and may be powered-off by gnome-disks. For me it's a good compromise between udisks1 and udisks2 behavior.

I'm ready to test and collect logs of my WD USB-HDD. I can't understand why Seagate drive unmounts all partitions before power-off, but WD does not.
What logs can help you to understand the problem?
