DBAN stands for Darik’s Boot and Nuke. It’s a software for permanent deletion of data and full hard drive erasure. The project is distributed for free in the form of a bootable image and is open source.
DBAN is based on the algorithms that include single- and multi-rewriting of hard drive space by pseudorandom number sequences that lead to total impossibility to restore data of the hard drive. The necessity of such procedure may appear before you want to sell your old PC or notebook, as an example. Also, this kind of actions may be required during hardware transfer from one organization to another or during work place arrangement based on old hardware. All this is usually explained by maintenance of sensitive commercial information, security measures and information protection.
DBAN has manual and automatic work modes. Among the manual available parameters of the program are various methods and numbers of cycles of HDD rewrite. So, disk erasure is made with the help of the DoD algorithm by default that is a part of the American national standard of the Ministry of Defense.
DBAN doesn’t have a graphical interface in the conventional sense. The program’s management is provided by keyboard. Along with that, to make the user’s work more convenient hotkeys are assigned in the separate area in the lower part of the screen.
It is easy to launch DBAN. The control elements respond in time and work correctly. But user has to be careful while using software like DBAN because the program was created to erase all the available HDD information.
