In case I should need to ensure that the data on a HDD is unreadable,
I would like to own one of the elephant killing pistols a pen pal from
Virginia owns. Sorry pal, that I ever joked about one of your guns,
regarding self-defense. Actually making a HHD completely forensic
useless, owning an elephant gun is very good.

My apologies!

Bcc: To that Virginian pen pal. :D

I'm an audio and video engineer, so I own degaussing gear that could
harm a HDD, but without granting to make it unreadable for digital
forensics cleanroom laser methods. A "Dirty Harry" alike gun could!
