What Randomly writing magnetic ones and zeros to a hard disk is called?

Answer 1

Randomly writing magnetic ones and zeros to a hard disk is called "disk formatting" or "low-level formatting." This process involves initializing the disk's surface to prepare it for data storage by creating a structure that allows the operating system to read and write data effectively. It can also refer to "data wiping" or "data sanitization," where existing data is overwritten to prevent recovery.
