after reading askubuntu as a guest for some time I decided to be an active part of the community posting here my first question.
I bought an HDD of 2TB some months ago. It worked ok, but when I was switching to exchange files between Windows 10 and Ubuntu 20.04 it was not working perfectly. Anyway I ignore that as I kind of made it work.
Today I tried to backup my Windows files in the HDD as I barely use that partition and it is using a lot of space. When I plug my HDD, Windows suggest the repair disk because there was some error in the HDD. I clicked yes and after 15 minutes of running the repair disk tool, It suggested me to format the disk as it was damaged. I did not format it and reboot my PC with Ubuntu (I am running dual OS Win10 original and Ubuntu 20.04).
After that my HDD is not auto playing anymore when I plug it, Windows does not recognize it and I have the following outputs in Ubuntu after trying some troubleshooting
~$ sudo fdisk -l
Output only for disk sdb

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.
I try opening gparted: ~$ sudo gparted /dev/sdb and the disk is unallocated and unrecognised disk label.
At some point I visualize that the type of disk is dos, but I dont see that output anymore
I have some data that I want to save in the disk but I am also open to format the disk if it is impossible to recover the data.
Any help is welcome.

1- WARNING! THIS WILL ERASE YOUR DISK >>> (sdb, 2TB)
fdisk /dev/sdb first, you need to delete. press d. then, press n, select primary (press p), select space number (select 1), enter, +1.9T enter. press w
2-
mkfs --type ext4 /dev/sdb1 if you get any error at this stage, you need to control file system
file -s /dev/sdb1 if there is a filesystem for sdb1, you have to delete it. after deleting it, run the mkfs command
wipefs -a /dev/sdb1 3-
mkdir /media/2TB1 4-a (temp way, you will have to do this after your new logins)
mount /dev/sdb1 /media/2TB1 4-b (perm way. do just once)
sudo nano /etc/fstab add this line to the file, then press ctrl+O enter and ctrl+x
/dev/sdb1 /media/2TB1 ext4 defaults 0 0 type
mount -a now, you can use your 2TB disk in ubuntu. if your aim is not formatting your disk, please let me know. we may road another way for you.
