0;To operate properly new disks must be formatted. Disks are organized as a series of compartments, called sectors, into which information is written and from which it is recalled. When you first take a new disk there is nothing at all recorded on it and before it amy be used, the sectors must be magnetically marked out on the surface of the disk. This is called formatting. It is analogous to drawing lines on a piece of paper before writing on it.
Procedure needed to make the drive ready for data storage and retrieval. At first, the drive is physically divided into tracks and sectors. Low-level formatting stays unchanged through the entire life of the drive unless the drive is re-formatted. The next level of formatting - partitioning - means dividing the drive into logical drives (C:, D:, E:, etc.). Every hard drive has at least one "primary partition" (C:) and may have many extended partitions. Finally, high level formatting creates a root directory, from which all other subdirectories could be created, and creates a File Allocation Table (FAT), which keeps track of all information on the disks and all relationships between different pieces of information.
