Similarly, this bug was not filed because of the mounting denial, but
rather because the denial lists the command for a potential dangerous
action without explaining what it would do and the data loss it could cause.

Title:
  Nautilus suggests option for mounting hibernated ntfs partitions that
  could lead to data loss

Status in NTFS-3G:
  New
Status in “ntfs-3g” package in Ubuntu:
  Confirmed

Bug description:
  --- What happens: ---
  If a user tries to open an ntfs partition that has been hibernated while using Nautilus they will be presented with this dialog:
  ------------------------------------------
  Unable to mount XP

  Error mounting: mount exited with exit code 14: Windows is hibernated, refused to mount.
  Failed to mount '/dev/sda3': Operation not permitted
  The NTFS partition is hibernated. Please resume and shutdown Windows
  properly, or mount the volume read-only with the 'ro' mount option, or
  mount the volume read-write with the 'remove_hiberfile' mount option.
  For example type on the command line:

              mount -t ntfs-3g -o remove_hiberfile /dev/sda3 /media/XP_
  -------------------------------------------

  The last suggestion, "mount the volume read-write with the
  'remove_hiberfile' mount option," is problematic because doing this
  would delete the 'hiberfile.sys' file and cause the user to lose all
  information on the saved session--potentially including unsaved work.
  Here is a selection from the ntfs-3g manpage explaining this option:

  remove_hiberfile
                Unlike in case of  read-only  mount,  the  read-write  mount  is
                denied  if  the  NTFS  volume is hibernated. One needs either to
                resume Windows and shutdown it  properly,  or  use  this  option
                which  will  remove  the  Windows hibernation file. Please note,
                this means that the saved Windows  session  will  be  completely
                lost. Use this option under your own responsibility.

  The fact that the exact command to do this is prominently displayed
  (and is the only command displayed) without any warning that this will
  delete the saved Windows session only aggravates the risk of data
  loss.

  --- What should happen: ---

  1. If a command is to be prominently displayed it should be the
  command to mount the partition in read-only mode (see command
  below)--this is the only completely safe way to mount a hibernated
  ntfs-partition without risking data loss.

                mount -t ntfs-3g -o ro /dev/sda3 /media/XP_

  2. A warning should be included in the Nautilus dialog which explains
  that using the 'remove_hiberfile' option to mount the drive in read-
  write mode will require deleting the saved Windows session and losing
  any unsaved files.

  --- Steps to reproduce: ---

  1. Hibernate a Windows installation
  2. Boot Ubuntu
  3.  Attempt to open the Windows partition using Nautilus
