$ # 硬盘Device Node为/dev/disk4s1

挂载

$ # 通过Device Node推出硬盘，但是不要拔掉移动硬盘连接
$ sudo umount /dev/disk4s1
$ # 创建一个目录，稍后将mount到这个目录
$ sudo mkdir ~/my_disk
$
$ # 将NTFS硬盘 挂载 mount 到mac
$ sudo mount_ntfs -o rw,nobrowse /dev/disk4s1 ~/my_disk
$ # 可以进行任意的写入操作了

推出

$ # 使用umount命令将NTFS硬盘从mac上推出
$ sudo umount ~/my_disk
