What is disk formatting?

Before we introduce unformat disk software, let's learn something about disk formatting. Disk formatting is a process of preparing a hard disk or other storage medium for use, including setting up an empty file system. When you format a disk, the Operating System erases all bookkeeping information on the disk, tests the disk to make sure all sectors are reliable, marks bad sectors (that is, those that are scratched), and creates internal address tables for later use to locate information. Every hard disk should be formatted before use.

Two levels of formatting:

Low-level formatting:

Low-level (closer to the hardware) formatting program will mark the surface of the disk with sector numbers and other information to be used later, in normal operations, by the disk controller. This is intended to be the permanent foundation of the disk, and is often completed at the factory. Almost all hard disks that you purchase have already had a low-level format. It is not necessary to format your disk through low-level format because it will physically damage the disk and cut short the life of the disk. Performing a low-level format erases all data on the disk.

High-level formatting:

High-level formatting is a process of writing the file system structures on the disk that let the disk to be used for storing programs and data. When you use high-level format to format disk, data on a disk is not fully destroyed. Instead, the area on the disk containing the data is merely marked as available (in whatever file system structure the format uses), and retains the old data until it is overwritten. So you still can recover data after format disk.
