有一块新买的1T的移动硬盘。买来格式化成ntfs后简单的分了几次区。 4G的硬盘PE，100G的快速交互，剩余800多G分成了两个对等的存储盘。
Debian 7.0 Wheezy 发布!
硬盘安装Debian7(Wheezy)以及初级配置
插到电脑USB接口后， 桌面自动弹出了4个盘符。 打开前2个都没有什么问题， 写读都正常。后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 at#unprivileged
大意就是这个ntfs-3g 没权限无法挂载，不管是不是root 。
现在我们来解决掉这个问题：
首先看看挂载， 先拔掉移动硬盘 执行 再插上执行， 会发现多了sdb3，sdb5

可以看到sdb是我的移动硬盘的， 但是只挂载了2个盘符。查看下硬盘现状

Partition table entries are not in disk order
注意看， 这里识别了Disk /dev/sdb 1000.2 GB
但是挂载出错了。 下面报了一个错，
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来重建分区表即可, fdisk 挂载设备， 然后f w 就可以更新分区表了。
