Say I have an old CD copy of a discontinued software product. What good will it do to shred it? As afar as I'm concerned, not worth the effort. Now if it has my personal financial data on it, or the data of any of my customers, it gets totally destroyed.
I would think that if you wanted to send one of the old BiaB hard drives to a recycling plant, using one of those apps that write pseudo-random ones and zeroes hundreds of times over would be sufficient.
I've used this when giving away old computers. I have an app called "Eraser" and I use the maximum security options.
