This is what the ntfs-3g manual has to say about it : Windows hibernation and fast restarting
On computers which can be dual-booted into Windows or Linux, Windows has to be fully shut down before booting into Linux, otherwise the NTFS file systems on internal disks may be left in an inconsistent state and changes made by Linux may be ignored by Windows. So, Windows may not be left in hibernation when starting Linux, in order to avoid inconsistencies. Moreover, the fast restart feature available on recent Windows systems has to be disabled. This can be achieved by issuing as an Administrator the Windows command which dis- ables both hibernation and fast restarting : powercfg /h off -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1481350 Title: Internal hard disk partition cannot be mounted manually To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntfs-3g/+bug/1481350/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
