前一次还挂载好好的，今天在挂载NTFS的分区就不行了，出现如下错误信息和提示：
$LogFile indicates unclean shutdown (0, 0)
Mount is denied because NTFS is marked to be in use. Choose one action: Choice 1: If you have Windows then disconnect the external devices by clicking on the ‘Safely Remove Hardware‘ icon in the Windows taskbar then shutdown Windows cleanly. Choice 2: If you don‘t have Windows then you can use the ‘force‘ option for your own responsibility. For example type on the command line: mount -t ntfs-3g /dev/sdb1 /media/sdb8 -o force Or add the option to the relevant row in the /etc/fstab file: /dev/sdb1 /media/sdb8 ntfs-3g force 0 0
解决方案已经列出来了，
一是：重启进入Windows，然后把硬盘安全移除，然后在进入Linux（我的是CentOS 7）就可以挂载了。
二是：强制挂载，示例：mount -t ntfs-3g /dev/sdb1 /media/sdb8 -o force，也就是在我们通常使用的挂载命令之后加上 -o force的选项即可。
