如何修复外置硬盘？

我想重新格式化我的硬盘，并在可能的情况下恢复（有些不重要的）内容。

我有一个带有 NTFS 分区的 Western Digital 1TB 硬盘。我拔掉了驱动器，而没有先安全地移除它。起初，一个弹出窗口要求我使用 Windows 操作系统来运行该chkdsk /f命令，但是，为了继续使用 Linux 操作系统，我ntfsfix在 ubuntu 终端上使用了该命令

现在，当我尝试访问硬盘驱动器时，它不再出现在 Nautilus 中。

我尝试使用磁盘工具重新格式化它，但它给了我一条错误消息，并且 Gparted 会无限地挂在“扫描设备”步骤上。

请评论您希望看到的任何输出，我会将其添加到我的问题中。

磁盘实用程序告诉我在 /dev/sdb 上

命令 sudo fdisk -l给出

This doesn't look like a partition table
Probably you selected the wrong device.

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   ?  1936269394  3772285809   918008208   4f  QNX4.x 3rd part

我在这里写错了，但是这里的输出fsck /dev/sbd是

dodohjk@DodosPC:~$ sudo fsck /dev/sdb
fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device&gt;
