Your testing with udisks1 is on an older version of Ubuntu (12.04 vs. 14.04) isn't it? If so, any chance you can install the udisks1 package on the same OS as you tested with udisks2? The packages are parallel-installable (and called 'udisks' and 'udisks2') so it should be as simple as 'apt-get install udisks' and then run "udisks --detach /dev/sdX".

I'm asking for this because I think this is due to a kernel and/or ntfs-3g problem.

Another thing to try would be to see if it happens if the filesystem type is *not* ntfs, e.g. try with ext4. (I realize this may not be possible as you may not want to reformat the disk.)

To recap, the only difference now from udisks1 is that udisks2 does not send SYNCHRONIZE CACHE before START STOP UNIT (it didn't work on any of my devices when I make the recent udisks2 changes). If it turns out that udisks1 works as expected on 14.04, I will try to add this change to see if it makes the difference...
