[Cialug] Semi-OT: wiping a hard drive once is enough?

[Nathan Stien]

Howdy Luggers,

In the above link, the author says that multi-pass hard drive wiping
programs are silly, because overwriting data once with zeroes is enough to
make it unrecoverable to forensics experts.  This is definitely counter to
what I have been taught, and I'm curious what y'all think about it.
