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.

Same behaviour for me. Although it only happens after the first time I select "Safely remove drive".
After the first automatic remount, the second time I choose "Safely remove drive" the usb external drive does not remount.

It happens for different types of USB drives and USB keys, so it's not related to a specific external drive.

Daniel Richard G. from Bug #507309 : usb-creator has a strange quirk in that when it starts up, it (re)mounts all unmounted partitions on all connected USB drives---even those drives on which the "Safely remove drive" operation has been performed, but are still plugged into the USB bus. This is with icons and everything on the desktop; this is clearly some sort of interaction with udev, similar to what occurs when a USB drive is plugged in.

I am filing this report to request that this "mount everything" behavior be removed. It is inappropriate for usb-creator to do this, not least because it may then go on to perform destructive operations on some of these newly-mounted filesystems!

I have the same problem, but only with two Western Digital USB 3 drives. The drives are My Book Essential 3 TB (WDBACW0030HBK) and My Passport Essential 500 GB (WDBACY5000ABK). I can reproduce the behavior on a laptop and a desktop, both running Ubuntu 10.10. All other drives remain unmounted.

In 11.10, I'm no longer seeing usb-creator remount previously-removed disks on startup.

I can't speak to the Nautilus behavior described in this bug, however, as I've never observed it myself.

As you can read on https://bugzilla.gnome.org/show_bug.cgi?id=641873 the specified behaviour seems to appear only with some nvidea chipsets.
Could the bug be a driver issue?

Nikhil P Joseph (madfly8082) wrote :

if it is a driver issue, is there anyway we can roll back to the driver version in lucid?

The behavior has changed, but still exists.

After "ejecting" the device, it now disappears and does not
automatically re-appear as a device; however, in "My Computer"
location when I select "Safely remove device" it disappears and
automatically re-appears. Interesting, after re-appearing I cannot
click on and open the disk drive.

At the OS-level the USB devices automatically remount, but at the
interface level it partially disappears, re-appears in my computer
inaccessible.

@torstenaf:

sounds interesting. Can you check your dmesg-log for entries like:

[ 968.188033] usb 1-8: new high speed USB device using ehci_hcd and address 6

and after reappearing (same bus):

[ 1005.992037] usb 2-8: new full speed USB device using ohci_hcd and address 4

If it's a driver issue there is definitively something wrong with the communication between ohci_hcd and ehci_hcd.

Tried again (as a while passed by and I am currently on 12.04): Still same issue.

Clicking eject in Nautilus seems to remove the device correctly, but disk usage analyzer for example still sees it - so that does not completely unmount the drive/device!

I consider this a critical issue as I am not always able to eject and in the next seconds find the correct plug - otherwise it is already remounted when I unplug it.

This problem has not gone away with

In fact, it is now worse because
Safely Remove Drive has been removed.
See launchpad #1067876.
So to safely remove my portable hard drive
I now need the following 4 commands:
> udisks --unmount /dev/sdb1
> udisks --detach /dev/sdb
wait for remount
> udisks --unmount /dev/sdb1
> udisks --detach /dev/sdb
Replace sdb with whatever your drive is using.
Add more udisks --unmount commands if you have
multiple partitions mounted.

When you click "Safely remove" on the launcher icon and then wait for buffers to be flushed, device remounts. The remount is done as a USB 1.x device as the speed is very slow on transfer (about 1MiB / minute). In the log (attached) it appears to think that the device is plugged into a slow speed hub.

Only affects USB 3.0 ports (2.0 safely removes ok).
The only way to unmount a USB hard drive in my case is clicking on the arrow icon on Nautilus window. If I click on Safely Remove, both on Nautilus or on launcher icon, the drive is re-mounted.

I would like to confirm what beni wrote on 2013-05-04.

I've just installed 13.04 on a zenbook with only USB 3.0 ports. "Safely Removing" USB harddisks or memory results in immediate re-mounting. Only clicking on the arrow in a Nautilus (or unmounting in a terminal "umount /media/...") will allow me to safely remove my disk.

My previous computer with 12.04 did not have USB 3.0 ports and I didn't experience this problem.

I have experienced the problem on 12.04 in the beginning, but went
away with some kernel update (currently running 3.5.0-30-generic which
works fine), so this might be the reason why you didn't experience it
on 12.04.

The USB/External drive remounts almost immediately after Safely Remove, but will properly unmount and stay unmounted after the second Safely Remove.

The same bug for me in Ubuntu 12.04.

Only eSATA port works. The other USB ports don't work at all.

The laptop I just bought last year meet the bug but the old PC in my home doesn't come across the bug.
After my time-consuming reflection, I suspect that the reason may be due to the problem in nautilus dealing with USB 2.0 and USB 3.0 port.

The nautilus doesn't deal well with USB 3.0 but deal well with USB 2.0.

Same bug with Ubuntu 13.04

Yesterday I updated from ubuntu 12.10 to 13.04 using the software updater.
Now when I plug-in my external hdd it automounts again in seconds after I hit 'safely remove'. It does not stay unmounted even after multiple times hitting 'safely remove' I can only remove it when I either do ' sudo eject /media/...' or 'sudo umount /media/....'

I hadn't had this problem with 12.10. It doesn't make a difference if I use the Usb 2.0 or 3.0 port on my computer.

In addition a Usb pen drive that was working perfectly before is not working at all anymore and not even listed
when I do 'sudo fdisk -l'

My computer does have a Nvidia Graphics card and I use gnome not unity

This is quite annoying! I'm using 13.10 and I just tried to safely remove a Samsung 1TB external drive (USB3.0 device plugged into USB3.0 port) but it kept remounting. I tried it this way as well:

sudo udisks --unmount /dev/sde1
sudo udisks --detach /dev/sde1

and that also remounted except it took a few seconds longer.

Here is my USB hardware info:

How ever I had the problem in 13.04 and 13.10 only on usb 3.0 and not 2.0.
Please solve the problem soon
This bug should atleast be of medium importance and please assign someone to it soon

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.

I have the bug on ubuntu 14.04 with my Seagate 1TB Backup plus extrnal hard disk. I had the same problem with ubuntu 13.10 .
The drive automatically remounted after safely removal/ eject in a few seconds.
This behaviour was only with the USB 3 ports of my laptop. Connectd to the USB 2 ports, the harddsik spun down and powered off as it should have.

I even tried using udisks to do the same but the result was the same.

Hope this bug is assigned to someone soon. It has been almost an year for me without a fix.

I have this problem as well with 14.04. The eject button in Nautilus works as I can see the device unmount from /media/username/DeviceName, then it immediately remounts. There are no errors with using "sudo umount /media/username/DeviceName", however the device will also remount.

I've also gotten the error "Cannot eject drive in use: Device /dev/sdg1 is mounted" until I close all Nautilus windows and reopen one, but this may not be related.

That workaround doesn't work for me. There is some activity on the drive light, however, it remains on with the motor running. The only thing that works for me is to close the notebook lid, wait for it to suspend, remove the drive, then open the lid again.

For me a simple

umount /media/<username>/<drive>

does the trick. The drive won't get remounted and is save to remove after the command completes.

Hope these observations lead to solution.

As of today I have installed all the update of and using Ubuntu 14.04.1 LTS

When I safely remove my external HDD in a 3.0 USB port it turns off for a second and then restarts and is mounted again.
The same does not happen when I plug my HDD to a 2.0 USB port.

As I have mentioned above, I have lost valuable data because of this bug, please fix it. I will help anyway I can.

I found two workarounds.

Workaround 1)
On Xubuntu 14.10 using Thunar 1.6.3 file manager I managed to stop the automatic remount of unmounted USB 3.0 drives using USB 3.0 ports.
In Thunar: Edit -> Preferences -> Advanced -> "Configure the management of removable drives and media." -> "Storage" tab:
I unchecked the "Mount removable drives when hot-plugged" option.
With this setting, after unmounting the USB 3.0 device in Thunar, 'dmesg | grep USB' has these new lines:
[ 1902.911399] usb 4-3: USB disconnect, device number 7
[ 1903.395819] usb 4-3: new SuperSpeed USB device number 8 using xhci_hcd

[ 1903.413049] usb-storage 4-3:1.0: USB Mass Storage device detected
The USB 3.0 external HDD stops for a second and starts spinning after that (like before unchecking the mentioned preference), the device can be seen in /dev/ but is not mounted. As a side-effect of this, thunar doesn't automount drives plugged in.

Workaround 2)
Instead of using the eject buttons, right-click -> "Unmount" each partition of the device in the file manager (I tested this with Thunar).

Robert B (robertb-macau) wrote :

This bug affects me too, on 14.04 (kernel 3.13.0-46).

However, the curious thing is that it only affects me with the new Transcend StoreJet 25H3 external HDD (USB 3.0) that I got recently. Before that I was using a Seagate external HDD (also USB 3.0) which I was able to safely remove (either using Nautilus or from the command line with udisks --detach). This seems to suggest that the drive itself is responsible for this behaviour.

The Transcend drive has a hardware button which on Windows is supposed to do a quick reconnect for a detached device, or a one-touch backup when connected. On Linux this button seems not to have any effect, but the fact that the drive can go from detached state back to attached state by its own action could possibly be the reason we're seeing this strange behaviour. Perhaps it's not a bug but a feature...

I have written my finding which might be relevant this bug: http://dhanar10.blogspot.com/2015/03/usb-hdd-gets-mounted-again-after-safely.html

It is on Debian 8 "Jessie" though, but it should be close to Ubuntu 14.04+ right?

I hope this bug can be resolved soon since it has been open for so long and it is affecting Debian, Ubuntu, and other derivatives also.
