If there is really big secrecy that you do not want to share with anyone in the world, destroy your disk by making serous damage to it – crash it with bricks or stones and make the inside disk to be pieces and then separate the pieces into different trash cans or bury them in different locations. This should be the largest secrecy you have ever buried and it won’t be discovered by anyone, any tool, any data recovery service.
