当我插入外部 USB 驱动程序时，我看到下一个提示：
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

这是我目前的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.

准确找出USB驱动器通过LSBLK:
nazar_art@nazar-desctop:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 149.1G 0 disk
├─sda1 8:1 0 148.1G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 1022M 0 part [SWAP]
sdb 8:16 1 7.2G 0 disk
└─sdb1 8:17 1 7.2G 0 part

└─sdc1 8:33 1 968.8M 0 part /media/sdc1
sr0 11:0 1 1024M 0 rom
这是 sdb1 - 这个外部 USB 驱动器。
再次尝试手动挂载：
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.
现在一切都可见了。
- 为什么会发生这种情况？
- 如何解决这个问题？
答案1
该错误表明尝试挂载文件系统时缺乏权限。我怀疑执行插件挂载的程序正在非 root 用户（可能是用于登录的用户帐户）下运行。
尽管 fstab 包含该users选项，但安装过程的一部分似乎仍然需要 root 访问权限。
要修复此问题，请以 root 身份手动执行安装。这应该可以完成这项工作：
sudo mount /media/sdd1
应该可以配置系统，以便执行挂载的程序以 root 身份运行，但这并不像听起来那么简单。
