I have a WDTV LIVE HUB in a cupboard but it produces a resonance sound which is traveling to the neighbouring bedroom. I've tried to dampen the sound with bubble wrap and foam packaging. But it's not working.

Any ideas how to fix it?

Suspend it with elastic? :)

Or change the volume of the box its in with some more 'stuff'. It may be that the distance between surfaces lays right where it needs to for the sinewave to get max effect

What's making the sound? HDD? Fan?

The Hard disk seams to be the main curplret. But it's a combination of both the hard disk and fan with worsening effect with the lid on.

If I apply pressure to the outer case the resonance stops.

The exauste fan is whisper quite when it's remove from its mount but becomes noisy when it's screwed back into it allocated position.

Replace with an SSD?

If its worse with the case on then perhaps try some car noise deadning stuff on the case? I forget what its called but its foil backed black gunky stuff to take the noise out of car panels.

That is such a good answer. However the WDTV Live Hub will only except WD BLUE SCORPION 1TB mobile hard drives. Somehow the firmware will only except WD drivers.

However it *might* except a WD BLUE SSD 1TB (WDS100T1B0A) but with a price tag of $480 it's a bit expensive.

Yeah, that would be an expensive solution. Generally speaking adding mass or decoupling the noisy culprit are two main approaches. As @richms says, some of that sound deadener may work if stuck on the case panels. Isolating items like the HDD and fan from the case with rubber or other soft mounts could also work. Could you mount the HDD externally?

Have you tried putting cloth under the feet? That works for my external hard drives at the back of my MythTV box. I have three bare hard drives on a wooden table, and they were quite noisy until I put a sleeve off some old flanellette PJs under them. If it is a case rattle, then stuffing folded over bits of paper between the rattling surfaces should work.

Try some carpet underlay - the proper waveform rubber stuff not the cheap foam. You should be able to get a small offcut from a carpet place for nix.
