- Darik's Boot and Nuke
- ---------------------
-
- Darik's Boot and Nuke ("DBAN") is a self-contained boot floppy that securely
- wipes the hard disks of most computers. DBAN will automatically and completely
- delete the contents of any hard disk that it can detect, which makes it an
- appropriate utility for bulk or emergency data destruction.
-
-
- Microsoft Windows Installation
- ------------------------------
-
- Double-click the 'install.bat' file.
-
- or
-
- Get the ISO file from the DBAN homepage and burn it to a CDR or CDRW disc.
-
- or
-
- Get WinImage from http://www.winimage.com/ and use it to write the IMG file.
-
-
- Unix Installation
- -----------------
-
- # dd if=dban-*.img of=/dev/floppy
-
- If /dev/floppy does not exist on your computer, then try /dev/fd0 or
- /dev/floppy/0 instead.
-
-
- Automatic Wiping
- ----------------
-
- Enter "autonuke" at the boot prompt to automatically wipe all devices in the
- computer without confirmation. Note that you may change the default behavior of
- DBAN by editing the 'syslinux.cfg' file that is on the floppy disk.
-
-
- Free Updates
- ------------
-
- If you wish to be automatically notified of DBAN updates, then go to
- http://freshmeat.net/subscribe/31200/ and subscribe to new releases.

-
- PRNG Seeding
- ------------
-
- Seeding the PRNG is optional. It is not required for DBAN to work properly.
-
- Darik's Boot and Nuke can load prng seeds from a floppy disk to improve the
- quality of its wipe. DBAN will check A:\DBANSEED for seed files when it starts.
- Seed files must be exactly 512 bytes in size, but they can have any name.
-
- (The acronym "prng" stands for "pseudo random number generator".)
-
- The system entropy pool will be very small when DBAN begins to wipe hard disks,
- so it is important to seed the prng whenever possible.
-
- If you are using a unix system, then run this command to make seed files:
-
- # dd if=/dev/urandom of=MySeedFile bs=512 count=1
-
- If /dev/urandom does not exist on your computer, then try /dev/random instead.
-
- If this command produces files that are smaller than 512 bytes, then your
- system entropy pool has been exhausted. Your system will replenish its entropy
- pool over time.
-
- If you are using a Microsoft Windows system, then you will need 3rd party
- software to make seed files. Consider using the Cygwin unix compatibility layer
- for Microsoft Windows. The Cygwin bash prompt can run the unix command given
- above. Download Cygwin from http://www.cygwin.com/.
-
-
- Logging
- -------
-
- Darik's Boot and Nuke will attempt to write a log file to A:\DBANLOG after it
- wipes the hard disks in a computer. Log files are in the tarball format. The
- average log file will be 5 kilobytes in size, which means that about 30 log
- files can fit onto the DBAN floppy itself.
-
- If you are using a unix system, then use this command to unpack the tarball:
-
- # tar -xzvf dban0000.tgz
-
- If you are using a Microsoft Windows system, then use WinZip or WinRAR to
- unpack the TGZ file. Also note that Notepad will not display the text files in
- the tarball properly, so use Wordpad instead. (Click Start, click Run, enter
- "write" into the box, click OK.)
