Yes, all that formatting does is rewrites some basic block marks and clears the tables. There are several applications that allow you look at what was on a disk before it was formatted.
However, there are also several applications that allow you to "wipe" a disk, writing random bits to the entire surface. In general, if you write 3 times with random data it will be virtually impossible to even read "shadows" of the data that was there before.
Hard disk formatting means preparing new space for data storage. This is by creating tracks and sectors in the disk.
Formatting prepares a floppy disk to store data
it does not divide a disk by necessity. you can chose, when formatting, to divide the disk into partitions, but this is not necessary. default is that you have no partitions (which is technically the same as 1 partition).
This is called "Disk Formatting" "Formatting"
Universal Disk Formatting
It wipes out data on the hard drive disk.
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.
When you delete a file on a filesystem all that is really done is that the disk "forgets" where the data is stored. It remains on the disk until it is overwritten. Formatting is a more technical term than most people understand. A common misconception is that formatting is simply deleting all data on a disc. In fact formatting is more of a "reconfiguration" of the disk. Formatting is the process where a system of data storage is applied to the disk. As a bi-product of this the system which remembered the layout of the origonal data is replaced and therefore the data inaccessible. It is however a common feature of most formatting tools to physically destroy the data as part of the formatting process.

No, backup is most certainly not that. Formatting is the process fo dividing the disk into tracks and Sectors.
Formatting
disk partitioning is the act of dividing a hard disk into multiple logical storage units referred to mas part ions to treat one disk as if it were multiple disks. disk formatting is the process of preparing a data storage disk for initial use.
