Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable , which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ...

The live cd iso file being installed needs to match the system being used; for 64-bit x86-64 processors amd64 is used, for 32-bit IA-32 processors i686 is used. [9] The supported architecture is listed at the end of the iso filename. The CD can also boot from a customized DVD which has almost 4.6 GB of free space for backed-up files.
nwipe was created to allow dwipe to be run outside DBAN, using any host distribution. It utilizes a simple text-based ncurses user interface or can be run directly from the command line . It is available as an installable package in the repositories of many Linux distributions , including Debian and Ubuntu .
As of version 11.11.11, Parted Magic supports x86-64 processors natively (32-bit x86 processors were previously supported), and requires a computer with at least a 64-bit Intel-compatible processor and 2GB of RAM.
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
All numbers in ISO 9660 file systems except the single byte value used for the GMT offset are unsigned numbers. As the length of a file's extent on disc is stored in a 32 bit value, [20] it allows for a maximum length of just over 4.2 GB (more precisely, one byte less than 4 GiB). It is possible to circumvent this limitation by using the multi ...
