log-files for my WD-HDD (Ubuntu 14.04 with udisks1 and udisks2)
Thank you for reply, David.

I have already installed udisks1 (1.0.4-8ubuntu1) on Ubuntu 14.04 and it works
as expected on all my drives if I unmount all partitions manually (from
console, Nautilus or Disks - it does not matter).

For me it seems that we have timing/race issue in udisks2.

I have 500Gb of data on my NTFS partition, so I do not want to reformat my HDD.
I'm sorry for this.

If there are no other differences - please add SYNCHRONIZE CACHE, I'm ready to
do a test and report back.
I prepared an archive of log-files for my WD-HDD on Ubuntu 14.04 with udisks1
and udisks2 installed.
The log-files are: "tailf /var/log/syslog", "gvfs-mount -o", "udisksctl
monitor", "udisks --monitor-detail".
The test-cases are:
1. udisks2 Safely remove from Disks (mounted) = FAIL - not spinned down
connect, auto-mount by Nautilus, clicked Power off in Disks, disconnect
2. udisks2 Safely remove from Disks (unmounted) = SUCCESS - spinned down
connect auto-mount by Nautilus, unmount in Nautilus, clicked Safely remove
drive in Nautilus, disconnect
3. udisks2 Safely remove from Nautilus (mounted) FAIL - not spinned down
connect, auto-mount by Nautilus, clicked Safely remove drive in Nautilus,
disconnect
4. udisks2 Safely remove from Nautilus (unmounted) = SUCCESS - spinned down
connect, auto-mount by Nautilus, unmount in Nautilus, clicked Safely remove
drive in Nautilus, disconnect
5. udisks --detach Safely remove (unmounted) = SUCCESS - spinned down
connect, auto-mount by Nautilus, unmount in Nautilus, sent "udisks --detach
/dev/sdX" in console, disconnect
On FAIL-cases there are interesting lines in "udisks --monitor-detail"
(udisks:2365): udisks-WARNING **: Couldn't call GetAll() to get properties
for /org/freedesktop/UDisks/devices/sdc2: Method "GetAll" with signature "s" on
interface "org.freedesktop.DBus.Properties" doesn't exist
may be it cause problems. I do not know.
I'm ready to test your new commits.
