Comment 58 for bug 1067876

Thank you, Martin!

For more accurate results I made a clean install of Raring on external HDD.

I updated gvfs to the latest version (1.15.4-0ubuntu1).
For USB flashes I have "/sys/block/sdc/removable = 0" and
and 'gvfs-mount -o' reports on Eject (from Nautilus or Unity) "Volume removed" or "Mount removed", device is still powered.
udisksd[2274]: Unmounted /dev/sdc1 on behalf of uid 1000
/var/log/syslog: kernel: [ 2507.403900] sdc: detected capacity change from XXXXXXXXXXX to 0

If I send manually 'udisks --detach /dev/sdc' after which 'gvfs-mount -o' reports "Drive disconnected".
/var/log/syslog: kernel: [ 2694.313868] usb 3-1.2: USB disconnect, device number 25

For USB HDD I have "/sys/block/sdc/removable = 0" and
 'gvfs-mount -o' reports on "Safely remove" (from Nautilus) or "Safely remove parent drive" (from Unity) "Drive disconnected", but HDD is still rotating.
/var/log/syslog: kernel: [ 2954.171781] usb 3-1: USB disconnect, device number 29
So device is removed from the /dev filesystem. So I can't --detach it with 'udisks --detach /dev/sdc'.

It seems to be a complex problem between udisks2 and gvfs, etc.
Two weeks ago I tested Fedora 18 and OpenSuSe 12.2 - they have 'Safely remove' broken too.

I dont think that there is something wrong with my hardware. You can make tests and collect all logs on your machine and compare the results.
