Low level formatting is a hard disk operation that should make recovering data from your storage devices.
racks and sectors
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.
"low-level" is imprecise here; all formatting is "low-level" anyway... That said, steer clear of utilities that specifically talk about 'low level' formats and were not made by your drive manufacturer, some of them can easily do damage to a drive for which they were not intended and which they do not properly understand.
There are two types of formating of computer can be done. (A).LOW LEVEL FORMATING (B).HIGH LEVEL FORMATING. LOW LEVEL FORMATING:which is done by the computer empire at the time of manufacturing.so when ever it is performed it is got as same as the newly built machines. And this type of formatting is done purely by software named "DISK MANAGER". HIGH LEVEL FORMATING:It is the formating which is done generally by us or any person using the window CD.
A low-level partition is a disk partition that has been low-level formatted. This means formatting in such a way that the data once stored in the partition is completely irrecoverable.
That would be called low-level formatting.

Low-level formatting
The three levels of formatting are:1. Low-level formatting - This is where the sectors and tracks are physically recorded onto the disk. PC builders once had to do this step, but now, nearly all hard drives come low-level formatted. In addition, you won't be allowed to do this, and if you are, the drive will never work again. The drives do not contain the necessary hardware for a successful low-level format. In most cases, if you try to send the low-level format commands, they will be intercepted and just the data areas will be wiped (high-level format), not the control (or "servo") areas nor the boundaries. The main exception here is floppy disks, and they are physically formatted each time they are formatted unless a "quick format" (high level only) is done.2. Partitioning - This makes the drive recognizable by an operating system and determines how much of the drive will be used for various purposes. For instance, you could have Windows on a partition and Linux on another. But even if you use the entire drive for one thing, you still have to have a partition table with at least one partition.3. High-level, or "logical" formatting - This simply wipes or at least verifies the data areas and adds the necessary file system structures (FAT, NTFS, Reiser, etc) in an empty state.A note about "low-level" commands found in the BIOS utility - This only rubs out all the data areas and destroys any partition table and filesystem. It does not actually do a low-level format of the drive (assuming PATA or SATA drives). It only returns the drive back to a condition similar to when it was purchased (with whatever wear it currently has) in that there is no partition table, filesystem, or user data. The low-level formatting is not touched.
high-level formatting
You can do a low level format ... this will not destroy all your files. To perform a complete formatting, you will need a system diskette or CD for that particular drive.
Low-Level formatting is used to outline areas (tracks and sectors) on the hard drive so physically the hard drive is ready to be used. So low level formatting is so called "PHYSICAL Formatting" which means all of your old data are physically wiped out and create a new structure on your disk. So when you add new data, it just add into your empty disk. High level formatting is so called "LOGICAL Formatting" which means that all the old data in your disk will not be completely erased (they are still in your disk) but the access path to those data has been wiped out. So you cannot access those data anymore (e.g. access path is like your address book. when you lost the address book, you won't know where your friends stay and can't contact them (same analogy)) However, your disk will show as empty. Okay, again when you want to store new data in your disk, it will create new access path and replace old data with your newly stored data. This formatting changes the file system on the hard drive so the Operating System that you use can write and save data to the hard drive.:)
