[Bug 506545] Re: possible fs crash in "hibernated" windows

I *think* it is this bug that has affected me twice recently.  Both
times Windows 7 had put itself into hibernate without me realising
(happened when I left the computer on overnight in Windows).  I then
continued to use Linux (and the NTFS partitions without problems).  When
I next booted into Windows I noticed strange errors, and some portions
of my hard drive were inaccessible when I was back in Ubuntu.  The
Windows disk-checking utility however managed to fix everything and
reported no bad sectors on the hard drive.

The volume that was affected was a separate NTFS volume (i.e. not the
one Windows was installed one), but one that I use regularly from within
Ubuntu (and whenever I'm in Windows).

This forum post might offer a possible root cause:

I don't really have the means to test this because my hard drives have
data on them that would be inconvenient to lose, but not critical enough
to back up.

Title:
  possible fs crash in "hibernated" windows

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

Bug description:
  Binary package hint: ntfs-3g

  Ubuntu 9.10, dual-boot with Windows 7.
  ntfs-3g 1:2009.4.4-1ubuntu4

  When Windows 7 is in hibernate mode, the partition is mounted in rw from Ubuntu, instead of ro, while 'man ntfs-3g' says:
  "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 for your own responsibility."

  So, after the writing to ntfs in that state and waking-up the Windows
  back, its filesystem became corrupted.

  It seems that ntfs-3g could not determine "hibernate" status in
  Windows 7.
