  Debian在挂载移动硬盘后,会出现有的分区能够识别,而有的分区识别不了提示报错的情况,遇到这个问题该如何解决呢?下面小编就给大家介绍下Debian挂载硬盘后分区读取报错的解决方法,希望对你有所帮助。

 Debian挂载移动硬盘后分区读写报错怎么办?

  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

  https://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,sdb5

  root@debian:/# cat /etc/mtab

  rootfs / rootfs rw 0 0

  sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0

  proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0

  udev /dev devtmpfs rw,relatime,size=10240k,nr_inodes=1015602,mode=755 0 0

  devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0

  tmpfs /run tmpfs rw,nosuid,noexec,relatime,size=813700k,mode=755 0 0

  /dev/disk/by-uuid/4c487d8c-396c-4601-b76d-eff7118d6775 / ext4 rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered 0 0

  tmpfs /run/lock tmpfs rw,nosuid,nodev,noexec,relatime,size=5120k 0 0

  tmpfs /run/shm tmpfs rw,nosuid,nodev,noexec,relatime,size=4446660k 0 0

  fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0

  rpc_pipefs /var/lib/nfs/rpc_pipefs rpc_pipefs rw,relatime 0 0

  binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,nosuid,nodev,noexec,relatime 0 0

  /dev/sdb3 /media/PE vfat rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=cp437,iocharset=utf8,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0

  /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。

  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。

  root@debian:/# fdisk /dev/sdb

  Command (m for help): x

  Expert command (m for help): f

  Done.

  Expert command (m for help): m

  b move beginning of data in a partition

  c change number of cylinders

  d print the raw data in the partition table

  e list extended partitions

  f fix partition order

  g create an IRIX (SGI) partition table

  h change number of heads

  i change the disk identifier

  m print this menu

  p print the partition table

  q quit without saving changes

  r return to main menu

  s change number of sectors/track

  v verify the partition table

  w write table to disk and exit

  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。

  df 看下挂载点成功挂载

  上面就是Debian挂载移动硬盘读取分区报错的解决方法的介绍了,你需要查看下移动硬盘的挂载状况,再使用fdisk重建分区,重新挂载即可。
