After following the instructions in other posts, I am still getting the same error when I try to mount my Windows 8 drive in Ubuntu 14.04 on a dual boot system. I have disabled fast start after shutdown, hybrid hibernation, and the preinstalled Asus Instant On service. I have tried restarting Windows rather than shutting down. In all cases I get the same error message:

Error mounting /dev/sda4 at /media/jesse/OS: Command-line mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/jesse/OS" exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda4': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option.

I did not have the same issue before upgrading from Ubuntu 12 to 14.

For what it's worth my computer is supposedly a "hybrid" with an SSD drive installed, although I can't see that the SSD drive is being used at all with my present settings. Any thoughts?

  • If you don't need to write on the Windows partition, you can mount it as read-only by executing in the terminal: udisksctl mount --block-device /dev/sda4 -o ro (sudo not required). Of course, this doesn't answer your question, but you may find it useful. –  Aug 22 '14 at 21:50

I had been able to do the read only mount, but needed to be able to save documents created in Ubuntu to my Windows drive. I was finally able to execute the command

powercfg /h off

in a Windows cmd session by choosing the Run as Administrator option when executing cmd.exe.

This solved the problem, albeit at the cost of disabling all hibernation options for Windows (including fast restart). I can now only sleep, restart or shut down in all menus and dialogs. Starting Windows takes noticeably longer, but my Windows 8.1 volume mounts fine in the Linux environment.
