if you have a hard drive from a windows computer that was in hibernation mode, and you need to mount the drive to access files, you can delete the hibernation file. you can tell ubuntu to delete the hibernation file and mount the drive anyway, giving you access to the files. by default, ubuntu will not let you mount a drive that is currently hibernated.
install ntfs-3g if you do not already have it installed.
sudo apt-get -y install ntfs-3g
mount the drive by specifying the device id and folder where you want the mounted contents to appear.
mount -t ntfs-3g -o remove_hiberfile /dev/sdf4 /home/user1/windoze/
done. the windows hibernation file has been deleted, and you can access the contents of the drive. be aware that deleting the hibernation file obviously means that any of the information that was being used at the time the disk was put into hibernation will be lost.
