I presume you meant DBAN when you listed MBAN ? Darik’s Boot and Nuke (commonly known as DBAN) 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 numbers generated by Mersenne twister or ISAAC (a PRNG). The Gutmann method is included with DBAN.
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 destruction, 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.
You can find the free CD/DVD version at this link.
there is also a product called eBan that will network boot the machines and wipe them that way
