A friend of mine gave me his external 2TB Seagate HDD which appeared to be somewhat faulty.
And, it is indeed pretty faulty.
First, I did try a lot of "common" commands, spent a few hours googling stuff, tried Linux and Windows (for chkdsk), opened the HDD case to plug it directly in SATA and I'll add that I do not need to recover the data, I just need to format it.
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1,8T 0 disk
Here, sda is the disk, its size, 1,8T seems correct.
In GParted, the disk only appears to be ~1.9GB. I can create a partition table but I cannot create a valid partition. And even if I could, it could only be 1.9GB.
dd if=/dev/zero of=/dev/sda

Do you have any idea? I guess the HDD may be dead, but I'm not quite sure.
What I find intriguing is the 1.8TB size with lsblk and 1.9GB elsewhere.
And again, I do not need to recover previous data (and since I did write a lot of 0's, they're probably gone for good :p). I just want to format the disk to make it usable again.
Thanks for your time :)
