I've been lurkning for a while. This is my first post.
I saw
this in another thread and it got me thinking.

Couldn't you use sand made out of aluminum? Or copper?
Does anyone have an idea of where you could buy metal "sand"?
Is there some obvious reason this wouldn't work? I don't wan't to fry my HD

this seems very odd to me. the first time you moved your computer you'd have a cyber-beach alll over your desk.

There was a thread about using copper dust in the forums. The search function will help you find it.

the metal 'sand' will conduct causing the pins on the chips to short - my hards hard exposed boards dont know about yours!

@jhh
I don't think the drive would take to well to having all it's drive circutry shorted by the metal dust
You'd have to keep the dust in an enclosure or a bag.
@powergyoza
Found it! Thanks. Hmm, it doesn't seem like anyone tried this method yet...
Oh, well. I think I'll sacrifice and old 500Mb drive to Hephaestus and how it goes.

Yeah, I'm still in the
rubber box mode of thinking... I like rubber for it's non-toxicity, ease of construction and low cost. If you try the dust, let me know how it works!

In case you couldn't tell
I'm pretty doubtful. sand/dust just isn't elastic to absorb vibrations - wouldn't a vibrating object just sink slowly to the bottom of the sand, until it touched the base of the enclosure and was no longer decoupled?
I don't know though, it's be interesting to hear now you get on.

Copper dust is quite pricey, $ 585 /5kg which should be enough for complete silence. Strong bags should be used so that no dust is leaked to cause shortcuts. It might be possible to find copper drilling industry waste dust for free...
