Debian 挂载移动硬盘后部分分区无法识别

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 测试体验 http://www.linuxidc.com/Linux/2013-05/84646.htmDebian 7.0 Wheezy 发布！ http://www.linuxidc.com/Linux/2013-05/83883.htm硬盘安装Debian7（Wheezy）以及初级配置 http://www.linuxidc.com/Linux/2013-06/86351.htm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 FUSE
library. Either mount the volume as root, or rebuild NTFS-3G with integrated
FUSE support and make it setuid root. Please see more information at
http://tuxera.com/community/ntfs-3g-faq/#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，sdb5root@debian:/# cat /etc/mtab

/dev/sdb5 /media/T1 fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0可以看到sdb是我的移动硬盘的，但是只挂载了2个盘符。

Syncing disks.这里就更新成功了分区表，因为我这是移动硬盘，上面并没有挂载操作系统OS，所以不需要更新挂载/etc/fstab 和/boot/grub/menu.list 这几个文件的对应挂载。再次执行fdisk -l 发现已经成功挂载，直接桌面可以直接点进去了。Disk /dev/sdb: 1000.2 GB, 1000204138496 bytes
