I pulled a 500gb hdd from a sky box and formatted it with a view to using as extra storage for a project but i do not think it is completely erased as it will now and then spin up despite not using it, at the moment it has 4 volumes i put on it but after formatting it said it was empty, all programs for the pc are on a ssd at the moment so what is your view as i do not want to buy another ssd as the pc is an old one.
