Mount an NTFS partition that cannot be accessed from Windows under Linux
About Windows 7, the computer installed Ubantu in the other partition (not allocated space under Win7). After installing Ubuntu, the user was not allowed to access the Windows 7 partitions by myself. Error mounting /dev/sda8 at /media/my/XXX: commandline ‘mount-t “ntFs-o” was not allowed
Solution:

Open terminal: If ntFS-3G is not installed, sudo Apt-get install NTFS-3G

Fix the appropriate partition for mounting errors such as /dev/sda8 in the prompt, enter:
sudo ntfsfix /dev/sda8
Just hit enter.
