装了Windows 8.1与Ubuntu双系统后，在Ubuntu系统下想进入Windows的某个NTFS分区，点击时却出现下面错误：
Error mounting /dev/sda2 at /media/love/Mis Archiivos: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/love/Mis Archiivos"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0). Metadata kept in Windows cache, refused to mount. Failed to mount '/dev/sda2': 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.
解决方案
使用ntfsfix这个命令解决，在软件包ntfs-3g中，因此需要先安装此软件包：
sudo apt-get install ntfs-3g
安装成功后，修复对应的ntfs分区（即错误中报出的分区名称）：
sudo ntfsfix /dev/sda2
