Smelt it!
Due to the recent MIT study concerning data recovery from old hard drives, we decided that the only fool proof means of data removal was complete destruction of the disk platters.
We started with two hard drives that had failed for various reasons. The data on the disks was sensitive, like most personal data you will find on any random hard drive. We had considered various methods of destroying the data. These methods of destruction included: detonation, shooting with high calibre bullets, bulk magnetic eraser, grinding the platters, smashing the platters with a hammer. These methods would all thwart a novice data recovery party, but wouldn’t be 100% effective due to scanning tunneling microscope recovery techniques.
We finally decided that the only sure way to thwart data recovery was to melt down all the aluminum contained in the platters. Slagging the drive would have two effects on the medium. First off it would convert it from a readable disk to any shape we decided to pour it into. Secondly it would nullify the magnetic properties of the coated aluminum.
