Nwipe was created out of my need to run the DBAN dwipe command outside of DBAN. This allows it to use any host distribution which gives better hardware support. It is essentially the same as dwipe, but with several feature improvements. If you're using DBAN, then you should really switch to Nwipe, as it is being actively improved rather than just maintained with the current features.
Nwipe is included in Parted Magic if you wish to use from a live CD. Update Aug 2016: sadly PartedMagic is no longer available for free. If you know of another live CD that includes Nwipe "out of the box", then please let me know.
