   Explanation: Why Linux can't open hibernated Windows partitions:

   You are seeing this error because you hibernated Windows instead of turning it off the normal way (in newer versions of Windows, hibernate might be the default option).

       Hibernating saves the current state information to the hard disk and then powers down the computer.
       Shutting down the computer closes all programs and ends all running processes before powering down the computer.

   When you turn off Windows by hibernating it, you are essentially pausing the system and saving all of that information (into a big file called hiberfil.sys) This way when you resume from hibernation all of your applications and files will be exactly how you left them. It also sets a flag in hiberfil.sys to let other Operating Systems know that Windows is hibernated.

   Making changes to your Windows (ntfs) partition while it is hibernated could be dangerous--it could cause Windows to not resume from hibernation or to crash after resuming. Because of this, the tool (ntfs-3g) that mounts (opens) the partition will not mount it in read-write mode if it sees a hibernation flag. As such, Nautilus, the default file browser, will not be able to automatically open this partition--hence the error message that you see--because it is trying to open it in read-write mode.

Workaround for all versions of Windows:

There are three ways to mount a hibernated Windows partition:

   Boot into Windows and power down the system by shutting it down completely. You may then boot back into Ubuntu and the partition will mount in read-write mode automatically when you open it in Nautilus. Note that the "Shut Down" option may not be the one displayed in your start menu by default. You may need to click the button next to it to see further options.

   Manually mount the filesystem in read only mode.

       Check to see if you have a mount point (folder for mounting your partition in) for your Windows partition in the folder /media using this command:

       ls /media

       If you don't see a folder for your Windows partition, you should create one with the following command:

       sudo mkdir /media/windows

       Next, mount the partition in read-only mode onto this folder with this command:

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

       Note that you should change /media/windows if your mountpoint is called something else.
       Now you will be able to view/open files on your Windows partition using any program in Ubuntu. However you will not be able to write to the partition or modify any files as it is in read only mode.

   If you need to mount the partition in read-write mode and are not able to or willing to boot into Windows and shut it down completely there is a third option. However, it is not included here because it completely deletes hiberfil.sys and will cause you to lose all unsaved information in the hibernated Windows programs.

If you want to terminate the hibernated session

sudo ntfsfix /dev/sdXY

where XY is the partition. ex: sda2 or sdb1
