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

AFAIK, leaving Windows 8 by selecting "restart" and rebooting to Linux
is safe. Also using the Windows dual-boot manager is safe, because it
syncs the cached data to disk before starting another OS. The unsafe
situation is booting directly into another OS through another boot
manager such as grub.

The test based on hiberfil.sys is only relevant for the Windows system partition. Testing the logfile is apparently better (mind the single quotes, and replace win8 by your mount point) :
head -c 30 '/win8/$LogFile' | tail -c 4 | od -t x1
If you get "01 00 01 00" you are in a safe situation, if you get "00 00 02 00" you are in an unsafe situation. This is to be confirmed, please report what you get.

You would guess that no ntfs-3g version if able to play the new rules,
so beware.

Bug description:
  Bug reported by Malbo (ubuntu-fr member): http://forum.ubuntu-

  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

  The Windows partition is mounted in write/read mode.

  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

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