Hard drive crash of the centry

One of the tasks I have at work, is to destroy the bad hard drives and wipe the good ones before they leave the company. This one failed when I tried to wipe it. I wonder why. The black stuff all around the drive is dust created from the scratching of the metal off the drive.

I have never seen a drive crash this hard. There are a few that I have seen with scratches, etc on the platters, but nothing like this.
