Darik's Boot and Nuke
Encyclopedia
Darik's Boot and Nuke is an open source
project hosted on SourceForge
. The program is designed to securely erase
a hard disk until data is permanently removed
and no longer recoverable
, which is achieved by overwriting the data with random number
s generated by Mersenne twister or ISAAC
(a PRNG
). The Gutmann method
, Quick Erase, DoD Short (3 passes), and DOD 5220.22-M (7 passes) are also included as options to handle Data remanence
.
DBAN can be booted from a floppy disk
, CD
, DVD, or USB flash drive
and it is based on Linux
. It supports PATA (IDE), SCSI
and SATA
hard drives. DBAN can be configured to automatically wipe every hard disk that it sees on a system, making it very useful for unattended data destruction scenarios. DBAN exists for Intel x86 and PowerPC
systems.
DBAN, like other methods of data erasure
, is suitable for use prior to computer recycling
for personal or commercial situations, such as donating or selling a computer. In the case of malware
infection, DBAN can be used before returning a disk to production.
The DBAN project is partially funded and supported by GEEP, an electronics and e-waste recycling company.

Data erasure is a software-based method of overwriting data that completely destroys all electronic data residing on a hard disk drive or other digital media. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to data disk sectors and make data...
a hard disk until data is permanently removed
Data remanence
Data remanence is the residual representation of data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written...
