And after reboot 'eject' became available in Thunar.
This is my small test:
1. Seagate Portable. Filesystem - one big NTFS volume. Eject from Thunar - no power-off. Disable volume and then eject from Thunar - disk power-offs. Umount volume and udisksctl power-off -b /dev/sde also spin-down disk.
2. U3 flash. Filesystem - one big FAT32. Eject from Thunar - flash power-offs.
3. WD Passport. Filesystem - one big NTFS. No power-off in all cases. Also no power-off in old udisks. I think that this disk may not support this feature.
