[Bug 1043149] Re: [regression since 12.04] ntfs-3g refuses to mount Windows8 not using hibernation

When the "fast restarting" of Windows 8 is enabled, the ntfs partitions
of internal disk (this means including non-Windows system partition) may
be left in an inconsistent state, and Windows 8 restarts using a saved
copy of the metadata (instead of what is actually on disk), leading to
potential data loss. The checks based on the hiberfil.sys cannot be
relied on, as this file only exists in the Windows system partition.
Also note that the "Shut down" button of Windows 8 does not show the
kind of restarting (fast or standard) which is triggered.

The only known way to avoid inconsistencies and data losses is to disable the fast restart and hibernation. See :

Title:
  [regression since 12.04] ntfs-3g refuses to mount Windows8 not using
  hibernation

Status in Release Notes for Ubuntu:
  New
Status in “ntfs-3g” package in Ubuntu:
  Confirmed

Bug description:
  Bug reported by Malbo (ubuntu-fr member): http://forum.ubuntu-
  fr.org/viewtopic.php?pid=10558721#p10558721

  HOW TO REPRODUCE:
  1) Boot into Windows8, use its "Restart" button
  2) From Ubuntu 12.04, try to mount the Windows8 partition:
  sudo mount -t ntfs-3g /dev/sdb8 /media/Windows8partition

  EXPECTED RESULT:
  The Windows partition is mounted in write/read mode.

  OBSERVED RESULT:
  The partition is not mounted. The output of the command is:
    Windows is hibernated, refused to mount.
    Failed to mount '/dev/sdb8': Opération non permise
    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/sdb8 /media/Windows8partition

  Remarks:
  - this bug is not present in 11.10
  - this bug is severe as it makes Wubi fail on Win8 ( Bug #1042159 )
