Hi, Chad.

Perhaps you're thinking of the following:

Years ago, at the I.D.A. research facility, near Fort Meade MD,
the protocol was as follows:

"Hard-disks" (which at that time were very-large platters) were
removed, deep grooves were scraped into them with a screwdriver,
acid was poured over them, and then thrown into a machine.

"Floppy-disks" and "Tapes" had a huge ceramic magnet (about a 150
pound-pull) passed over them (as close to the flatest-surface
as possible) to degauss, and then, they were throwm into a machine.

"Files", ie, papers, were burnt, and then thrown into a machine.

The machine, which took-up almost an entire room, was un-officially,
(but very-descriptively), called a "duster".

Regards, Gregory.
