Degaussing is not %100 fool proof. You can have a careless employee forget to turn on the machine and think a drive is wiped send it out and next thing u know your on the bad end of an expensive law suit.
Shredding is 100% fool proof. throw it in the big grindy thing, out pops shards.
I have found that people prefer physical destruction rather than magnetic. Not sure why but i think that unless they see it or know the actual drive will be destroyed than their data might still be their?
I use a log splitter. Its so much fun!
