I just unplugged my portable WD hard drive without doing safe remove. I think that action of mine just corrupted my hdd.

I did the following: sudo fsck /dev/sdb1

and I got the following result: `

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>

I didn't really understand what that means. Can anyone guide me what to do??

first: your drive is not NTFS ? you reformatted it to EXT4?

  1. if it is NTFS (default file system)
    fixing NTFS with windows chkdsk is best but this command works

    sudo ntfsfix  /dev/sdb1

    NTFS-fix help

  2. if it's EXT4/EXT3/ext2 (you reformatted it)
    then the super block is corrupt

it's saying the default super block is corrupt so it can't check it,
then is tells you to try a different super block,

tools like testdisk can be useful to restore a good super block,
