Unformat

Disk format is the process of preparing a hard disk or other storage medium for use, including setting up an empty file system. Formatting a disk involves two quite different processes known as low-level and high-level formatting.

High-level formatting: a process of writing the file system structures on the disk that let the disk to be used for storing programs and data.

Low-level formatting: a process of formatting disk surfaces and installing characteristics like sector numbers that are visible to, and used by, the disk controller hardware.

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. A high-level format will suffice for most purposes by wiping out the control structures and writing new ones. The old information is lost and the disk appears as new after a high-level formatting.

Unformat means recover everything from the newly formatted disk. However, high-level format can be unformatted while low-level format can not.

Can you imagine the situation when you accidentally format disk and lost the important data? Usually, people format seemingly unnecessary disks only to find out that they really need them later.

When you encounter such case, you have to recover the lost information.
