My Flash drive is corrupted and I am trying to recover it using this answer in ask ubuntu whose link is this https://askubuntu.com/a/37775/658451. I have tried 

   lsblk
sudo blkid
sudo fdisk -l

and here is the result snapshot enter image description here

my targeted drive is sdb of size 14.5 GB

But when I try to mount a mountpoint I got an error which is

mount: /media/moeed/usb: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.

I have also tried 

pmount /dev/sdb

I got this error on it

NTFS signature is missing. Failed to mount '/dev/sdb': Invalid argument The device '/dev/sdb' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? NTFS signature is missing.

Kindly Help me recover the drive. If you need any other information please tell me. Thanks :)

  • @JoKeR I have tried to fix the ntfs partition by using sudo ntfsfix -b -d /dev/sdb but I got an error saying NTFS signature is missing. – Moeed Azhar Mar 06 '18 at 16:03

The problem was done with merely few steps after trying a lot. Just open DISK and the usb drive was shown in it. I tried to format from here and my drive was mounted after few seconds :) Thanks all for your help.

Could you use gparted to reformat it to fat32? It doesn't need to be mounted for that? Sorry if it's a stupid answer, I just thought it might work!

To install gparted:

 sudo apt-get install gparted

To use it:

sudo gparted
