Não é possível montar o driver USB externo - no Ubuntu 12.04

0

Quando eu conecto o driver USB externo, vejo o próximo prompt:

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

Este é o meu atual sudo fdisk -l :

Description: read/write NTFS driver for FUSE
 NTFS-3G uses FUSE (Filesystem in Userspace) to provide support for the NTFS
 filesystem used by Microsoft Windows. It can:
 .
  * create, remove, rename, or move files, directories, hard links, and streams;
  * read and write files, including streams, sparse files, and transparently
    compressed files;
  * handle special files like symbolic links, devices, and FIFOs;
  * provide standard management of file ownership and permissions, including
    POSIX ACLs.
 .
 This package also contains the tools previously available in the ntfsprogs
 package.

Descobrir exatamente o drive USB através de lsblk :

nazar_art@nazar-desctop:~$ lsblk

└─sdc1   8:33   1 968.8M  0 part /media/sdc1
sr0     11:0    1  1024M  0 rom

É o sdb1 - este drive usb externo.

Tentei novamente montar manualmente:

nazar_art@nazar-desctop:~$ sudo mount /media/sdb1
[sudo] password for nazar_art: 
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.

Agora tudo é visível.

- Por que isso acontece?
 - Como resolver este problema?

O erro está indicando uma falta de permissões ao tentar montar o sistema de arquivos. Eu suspeito que o programa que executa a montagem no plug-in está sendo executado sob um usuário não raiz (provavelmente a conta de usuário usada para efetuar login).

Embora o fstab inclua a opção users , parece que uma parte do processo de montagem ainda requer acesso root.

Para corrigir, execute manualmente a montagem como raiz. Isso deve fazer o trabalho:

sudo mount /media/sdd1

Deve ser possível configurar o sistema para que o programa que executa a montagem seja executado como root, mas isso não é tão simples quanto parece.
