我只是拔掉了我的便携式 WD 硬盘，而没有进行安全删除。我认为我的行为刚刚损坏了我的硬盘。
我做了以下事情：
sudo fsck /dev/sdb1
我得到了以下结果：`
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
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/sdb1
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>
我不太明白那是什么意思。谁能指导我该怎么办？
