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??
