Throwing away an old hard drive?
Stroke the exposed circuit board with a pp3 battery, and then sweep around the casing with one of those really powerful rare-earth magnets. This will prevent people from finding your bank details, old emails, plans for terrorist attacks and your collection of donkey-induced snuff movies.

or just drill a hole in it.
And if you can't be arsed doing that and it'll still spin up, download ccleaner and wipe the drive a few times with a defrag in-between each one, good luck to anyone trying to get anything off that.

I just smuggle mine into MRI scanners, simple.

If the drive still works, but simply needs disposing of
Use DBAN or the Linux 'wipe' command from a LiveCD

If it's broken the only totally accepted way is to melt all the platters into a lump, and burn the PCB.

NB: The above is only really needed for the really unforgivable porn or disks containing people's details and such. But if it's at work there's plenty of places you can hire a degausser.

how about
just smashing it to fuck with a hammer?
Where the fuck am I supposed to get 'one of those really powerful rare earth magnets' from?
The superhero weapon shop? Maybe I'll pick up a baterang and some kryptonite while I'm there.

and 'smashing it to fuck'
is sooo therapeutic.
Just don't do it in your office which just happens to be above a lecture theatre.

rare earth magnets
are made from neodymium. I got one off ebay for about £2.50 and it's about the size of a 10p coin, but slightly thicker.

There are two of them in most harddrives too.

I half buried one
in the freshly laid concrete of some new houses.
Just left one corner peeking out about an inch or so.

Never revisited to see what they had done with it.

Not sure the magnets will work.
They ought to, I suppose, but given the inverse cube law they may not get close enought to wipe the drive.
The battery may well kill the controller -- but there are plenty of people who can move the platters to another enclosure.
Personally, I'd either overwrite in a DOD-type manner and/or destroy the drive.
