We actually dissected one before, he liked it and we indeed took the
magnets out (and shiny platters). They are a little stronger than eBay
magnets, but not my as much as to justify their weird shape, for
actual use.

My 25+ year old shop vac had the cheap plastic dolly go bye-bye so I
cut a circle and square of particle board and glued them together.
Casters on the bottom of the square and two HD magnets set flush with
the top of the circle which fits inside the welded seam on the
canister. Of course this won't help the newer all plastic units but it
does the job on my antique.

Larry, you're just...not right!

Ah, acknowledgement at last! David Bowie once said

I'm not quite right at all. (Am I?)

I always identified with that.

Ta!

Yup, I have a Windows NT CD on my cubical wall that has had just that
done to it.

Then I hit it with a sledgehammer, expecting part to fly away and to see

Barely any damage was visible on the drive (though, probably, it would no
longer function). After many more hits, finally, the hard drive was
shoring visible deformation of its frame. I am rather amazed as to how
tough the hard drives are.


That's because you're trying to squash a casting.

Try setting the drive on its edge and whacking it, but be sure to
take safety precautions, because it will probably fly across the
room. Maybe clamp it to an angle plate.

Or, get a sledge with a pointy peen, if there is such a thing.

But why smash it? Why not just open it up, salvage the supermagnets,
and bend the disk? And, with modern drives, as soon as it's open
to room air, it'll be pretty much useless for data - the last time
I worked with flying heads, they flew at less than 0.000050", which
is smaller than dust.

Cheers!

I did that, and no, it did not fly apart.

Too time consuming, I already have enough magnets. I did take a hard
drive apart before.

Most of the military manuals, especially the improvised anything ones,
are only trustworthy if accompanied by the training that would have gone
with them when they were issued to those that needed them.

As stand alone knowledge bases, the ones I have seen, left a bunch to
be desired, and were written on the premise that the reader already knew
many important things.

That would explain the Operations section of the U.S. Army manual of the
Burke #4 horizontal mill:

OPERATING INSTRUCTIONS

" The operation of the Burke #4 Milling Machine is so simple that no
specific instructions are required "

The machine was simple and the guys that were expected to operate it
were expected not to be as simple as the machine.

I was referring to the large number of explosives "manuals" that are
reprinted an distributed widely about the web.
