[Bug 792085] Re: Automatic remount of safely removed drive

[Nick Sharp]

I have this problem on 12.04 with a new Seagate 3TB usb3 external drive
ON A USB3 interface.  Will test later on 14.04; waiting for final
release at present.

For me, safe removal never works (drive always returns) unlike others
above, who find it does work second time.

I reduced the problem a little by:

System Settings/Details/Removable Media/Never prompt or start programs
on media insertion (TICK)

and dconf-editor:

org.gnome.desktop.media-handling 
automount (UNtick)
automount-oepn (UNtick)
automount-never (TICK)

Of course, then I have to open disk utility and mount drives by hand and
open the mount point by hand.  No big deal.

Interestingly, the problem does not occur if the drive is connected via
a USB2 interface, but that rather spoils the point of having a
USB3-capable drive!  In fact, it dropped the read time to about 1/5th
but made almost no difference to the write time, so if your use of the
drive is primarily to archive files, it seems: connect via USB2
interface is quite a good idea for now!

I suspect that the issue is related to the USB3 interface, both in the
drive and the PC.

A Seagate ST2000DM001 (2Tb USB interface) external drive CONNECTED ON A
USB3 INTERFACE DOES behave correctly on SAFE REMOVAL and does NOT
reappear in the  list in disk utility.

(probably off topic) It is interesting to note that on my drive (Seagate
STNV3000300) the interface at the disk enclosure is a PAIR of connectors
side by side, not a simple mini or micro USB peripheral interface.

Title:
  Automatic remount of safely removed drive

Status in “nautilus” package in Ubuntu:
  Confirmed
Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: nautilus

  When I choose "Safely remove drive" context menu entry for an external
  USB drive within a nautilus window or directly clicking on the desktop
  icon, after about 10 seconds the drive is automatically remounted and
  a Nautilus window showing the root folder opens.

  I have noticed that similar already happened with a very old Ubuntu
  version - Bug #110589 and as that is so long time ago I thought it is
  better to open a new bug. Reason of the problem might even be
  completely different.
