dd: clean your drive securely

Now like anybody I’m a BIG fan of wiping old drives using dd but sometimes there’s a tool out there that will do most if not all of the work for you. Cue DBAN. OR as the site says:

Darik’s Boot and Nuke (“DBAN”) is a self-contained boot disk 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.

Complemented with TrueCrypt you will have a mighty secure setup. Possible / definite paranoia issues too… But your data will be secure. For the more command line orientated the old reliable dd if=/dev/urandom of=/dev/disk bs=1k is good enough imho. (It puts random bits in place as opposed to a regular pattern. Not that it will stand up to NSA level scrutiny but it’s more than enough for most data recovery…)
