ATA secure erase UNLOCK
Running the ata secure erase command with gnome disk is currently dangerous as a hard drive reboot for whatever reason during the erase procedure would have the drive locked and unusable.
Please add a feature to disable the security set on the drive so if this happens, users can unlock. At the very least, show the password it uses to set security.
I had this happen to me in the past. It doesn't even tell you what password it sets so it took some googling.
