You need to wipe a disk with random patterns of 0's and 1's 6-8 times before
the data is unrecoverable (by someone like ontrack).
/dev/zero is OK, I wonder if you could use /dev/random...
If you think that's being paranoid, do a search with google on people
recovering data from formatted hard drives.

I know that NASA's requirement is fulfilled by writing /dev/zero to
partition s2. Does anyone on this list see a problem with that? Does it
have be done a few times to beat down the residual magnetic flux?
