Format read-only USB Drive

I was trying to format a read-only USB Drive without any success. I'm currently using Xubuntu 18.04 LTS. I was trying :

sudo hdparm -r0 /dev/sdc

I'm getting :

readonly      =  0 (off)

but then I'm running gparted:

sudo gparted

and I'm getting :

Can't write to /dev/sdc, becuase it is opened read-only.

Frustrating :)
