Cannot mount volume

Bug #163962 reported by Ken Jannot on 2007-11-20
Affects Status Importance Assigned to Milestone
gnome-volume-manager (Ubuntu)

Bug Description

Gutsy Gibbon will not recognize any drive except the one it is installed on. It sees the drives, but cannot read them. When I try to open the folders, I receive the message, "Cannot mount volume." When I go into the partition editor, I see the message, "Unable to read the contents of this filesystem" for those drives. Again, I had no troubles under Feisty--but now with Gutsy, I cannot access these drives.

Thank you for your report

Could you detail the steps you take to get to the partition editor


could you please attach your /etc/fstab file


and could you please attach the output of this command df -k

mount is/was doing what it was told to do. (by fstab and gnome...)

I get this same error. I'm running 64-bit Ubuntu 8.10. I open Partition Editor from the menu and look at /dev/sda. The first item listed there is /dev/sda3. It's a 214GB NTFS primary partition. There's a yellow warning triangle next to it, and its Windows label (CURRENT) isn't shown. When I double-click on it, or when I right-click on it and choose Information, I get an indication that it is not mounted and a statement, "Unable to read the contents of this filesystem!" It is a working partition that I was just using in WinXP before rebooting into Intrepid on this dual-boot AMD system. I did a normal shutdown and reboot when leaving WinXP; no system reset or anything like that.

In Nautilus, when I click Computer and then double-clicke on CURRENT, I get this:

  Cannot mount volume.
  You are not privileged to mount the volume 'CURRENT'.

After a few seconds, I get a dialog that says this:

  Opening "CURRENT".
  You can stop this operation by clicking cancel.

A few seconds later, I get this dialog on a different desktop:

  Unable to mount location
  DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Double-clicking opens the other NTFS partitions on this system without difficulty.

I can't get at this partition with these steps:

  sudo -i
  [browse to /media]

That doesn't work because CURRENT is not shown as one of the partitions there, and when I click on Computer at that location, I get this error:

  Could not display "computer:".
  Nautilus cannot handle "computer" locations.

I have added a line to my /etc/fstab that attempts to mount the partition, but it's not working. The fstab is:


# /etc/fstab: static file system information.
# -- This file has been automaticly generated by ntfs-config --
# <file system> <mount point> <type> <options> <dump> <pass>

proc /proc proc defaults 0 0
# Entry for /dev/sdb5 :

# Entry for /dev/ !! UNKNOW DEVICE !! :

/dev/sda5 /media/BACKROOM ntfs-3g defaults,locale=en_US.UTF-8 0 0
/dev/sda3 /media/CURRENT ntfs-3g defaults,locale=en_US.UTF-8 0 0


Not sure what that "UNKNOW DEVICE" line is all about.

df -k gives me this:
