有一个新的团购1T移动硬盘。购买格化学式ntfs经过几次简单的子区域。 4G硬盘PE。100G高速互动，盈800许多G分为两个相等的存储盘。
到您的计算机USB接口后，， 桌面弹出自己主动4一封信。
打开前2一个本来没有问题。 写读一切正常。面两个一双击就会报错：
Error mounting: mount exited with exit code 1: helper failed with:Unprivileged user can not mount NTFS block devices using the external FUSElibrary. Either mount the volume as root, or rebuild NTFS-3G with integratedFUSE support and make it setuid root. Please see more information athttp://tuxera.com/community/ntfs-3g-faq/#unprivileged大意就是这个ntfs-3g 没权限无法挂载。无论是不是root 。
如今我们来解决掉这个问题：
首先看看挂载。 先拔掉移动硬盘 运行 再插上运行， 会发现多了sdb3，sdb5

能够看到sdb是我的移动硬盘的。 可是仅仅挂载了2个盘符。
查看下硬盘现状

可是挂载出错了。 以下报了一个错，
Partition table entries are not in disk order
说硬盘分区表不在硬盘的顺序里面，意思就是移动硬盘的分区表乱了。
既然是这样就简单了。 用fdisk来重建分区表就可以, fdisk 挂载设备， 然后f w 就能够更新分区表了。

再次运行fdisk -l 发现已经成功挂载， 直接桌面能够直接点进去了。
