The process of initializing these logical blocks on the physical disk platters is called low-level formatting, which is usually performed at the factory and is not normally changed in the field. As a next step in preparing an HDD for use, high-level formatting writes partition and file system structures into selected logical blocks to make the remaining logical blocks available to the host's operating system and its applications.The file system uses some of the disk space to structure the HDD and organize files, recording their file names and the sequence of disk areas that represent the file.
