Sounds like an idea.. I do have access to a drill press too.

Not for shredding, though I've heard rumors that if you know the right people in Principal or Wells, you can merge your drives with theirs. 

What I've done is drill them (two hits through the platter, pop pop) and drop them off at the recycling place behind the comic shop (University + 73rd) for recycling.

As another (although not free) alternative, is anyone aware of someone in the Des Moines area that can shred drives? We have ~100 sitting in a box that need to be destroyed. Some of those don't even work anymore.

what he said :) 

if you don't have some regulation/compliance standard to adhere to, 
shred/dd should be sufficient. if you do have a standard, do whatever 
it says :)
