Erasing a hard disc (i.e. spinning rust, not solid state ones) before retiring it is a proper use case. Linux/Unix example:
dd if=/dev/urandom bs=8mb of=/dev/sda
Note: this is a trivial example, which could be optimized in various ways, e.g. by generating one 8mb file of randomness and reusing that, especially if your urandom is slow.
