损坏的外部硬盘

Question

当我意外地拔出我的外部硬盘驱动器时，我正在用grsync做一个备份。

结果是它不会再上山了。我知道这个错误：

我试着运行sudo fsck /dev/sdb，结果并不乐观：

e2fsck 1.42.12 (29-Aug-2014)
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 valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
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>
 or
    e2fsck -b 32768 <device>

因此，我运行了建议的命令: sudo e2fsck -b 32768 /dev/sdb

e2fsck 1.42.12 (29-Aug-2014)
e2fsck: Bad magic number in super-block while trying to open /dev/sdb

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
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>
 or
    e2fsck -b 32768 <device>

任何想法。理想情况下，我希望恢复磁盘上的内容(非常多，事实上！)

Answer 1

方便的工具"testdisk“将对您的磁盘进行非常彻底的扫描。它还包括photorec，这将帮助您在数据恢复之前，您可以再次分区磁盘。

请查看这篇文章，以获得适合您恢复需求的其他工具列表。。

Answer 2

我有一个USB棒，因为某种原因而损坏了，而且不会挂载。我用G-parted重新划分驱动器。一旦它被重新划分，它就会挂载。

可能帮不上忙，因为你很可能想把数据保存在你的外部驱动器上。
