Debian掛載移動硬盤後分區讀寫報錯怎麼辦?

  Debian在掛載移動硬盤後,會出現有的分區能夠識別,而有的分區識別不了提示報錯的情況,遇到這個問題該如何解決呢?下面小編就給大家介紹下Debian掛載硬盤後分區讀取報錯的解決方法,希望對你有所幫助。

 Debian掛載移動硬盤後分區讀寫報錯怎麼辦?

  插到電腦USB接口後, 桌面自動彈出了4個盤符。 打開前2個都沒有什麼問題, 寫讀都正常。後面兩個一雙擊就會報錯:

  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

  大意就是這個ntfs-3g 沒權限無法掛載,不管是不是root 。

  現在我們來解決掉這個問題:

  首先看看掛載, 先拔掉移動硬盤 執行 再插上執行, 會發現多了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

  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是我的移動硬盤的, 但是只掛載了2個盤符。

  查看下硬盤現狀

  Partition table entries are not in disk order

  注意看, 這裡識別了Disk /dev/sdb 1000.2 GB

上一頁12下一頁共2頁

  但是掛載出錯了。 下面報了一個錯,

  Partition table entries are not in disk order

  說硬盤分區表不在硬盤的順序裡面,意思就是移動硬盤的分區表亂了,

  既然是這樣就簡單了, 用fdisk來重建分區表即可, fdisk 掛載設備, 然後f w 就可以更新分區表了。

  這裡就更新成功了分區表, 因為我這是移動硬盤,上面並沒有掛載操作系統OS, 所以不需要更新掛載/etc/fstab 和/boot/grub/menu.list 這幾個文件的對應掛載。

  再次執行fdisk -l 發現已經成功掛載, 直接桌面可以直接點進去了。
