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

[Nathan C. Smith]

IF you are protecting yourself from the neighbor kids once might be enough.  To protect yourself from your own government and large organizations, it must be re-written multiple times.  or it can still be read.

To be certain, drill some holes in it.

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.
