I however prefer the Peter Gutmann Disk Wiping Procedure. DOD only recommends 3-7 passes for disk wiping compliance. Gutmann recommends 35 passes.

I have read articles where trained professionals have been able to recovers bits of data after as many as 26 multiple pattern wipes. I'm sure the data was miniscule, but nonetheless recovered.

Some people do this manually with a linux boot disk and the dd commands by running a wipe of alternating between zeros and random data.

#~> dd if=/dev/zero of=/dev/hda
#~> dd if=/dev/random of=/dev/hda

But it takes a lot longer.
