Formatting
A low-level format is the process that marks the location of tracks and sectors on a disk. A disk cannot be partitioned or formatted until a low-level format is completed.
Bits. Groups of bits are organized into sectors or blocks, which are further grouped into clusters, which are further grouped into tracks.
A disk cluster is a location on a disk's surface that stores data. Most disks are divided into platters/cylinders, tracks, and sectors, and sectors are grouped into clusters when formatted with a file system.
It uses tracks and sectors to find certain pin points on where the data is. Some of the spots are reserved for certain files.
Hard disk formatting means preparing new space for data storage. This is by creating tracks and sectors in the disk.
Zone Bit Recording (ZBR) is used by disk drives to store more sectors per track on outer tracks than on inner tracks.
