Destroying hard disks

[ffutures]

As part of the mega-clearout I've begun I want to get shot of some old hard disks - apparently dead, but for all I know the data can still be recovered, and they contained things like user registrations for Forgotten Futures. I don't think there's anything else particularly sensitive on them, but I'd prefer not to take a chance.

My main ideas for disposing of them are either to dismantle them with a large hammer or bake them for an hour or two and hope that erases the platters. I don't have a big electromagnet, which would be another obvious method. Any ideas?

Think I'll just smash the electronics as suggested by another comment - it's probably enough to meet the legalities.
