We've talked in the past about secure data erasure, using things like DBAN
which use wiping algorithms approved by the US DoD. The BBC news website is
carrying a story today encouraging people to get physical and smash their
drives. Now, whilst I can see that putting a hard disk that has come
straight from a computer on ebay, or one that has been trivially formatted
or had files "erased" is probably a risk, is it really worth getting people
to attack their hard drives with hammers? (Never mind the Health & Safety
implications!)
