issue with ECI-2, CXN v2 and external 2.5" HDD

Hello,
I'm looking for an explanation regarding the following issue, please.


2.5" HDD -> CXN v2 -> ECi-2


I'm playing WAV files from an external 2.5" HDD (does not have external plug for power, it is takeing power via the same USB port) that is connected to a Cambridge CXN v2. The CXN is linked to Electrocompaniet ECI-2. The problem is that regarding the selected input of the ECI-2, I have a very disturbing noise in the speakers. When the hdd platans starts to spin I can hear that sound in the speakers. The noise is not rising if I increase the volume. It remains constant. It's like I would have a microfon placed on the top of the HDD.
I tried 3 different amps and the disturbing sound was not present. Only when I use the ECI-2 as amplifier. But, if I use and external 3.5" HDD with external plug charger the problem is solved. I played some music from a CD player connected to ECI-2 and the sound is clean, there is no noise.
My question is who's fault for this issue is? Cambridge CNX v2 for sending some brum, noise or the Electgrocompaniet ECI-2 for not having some filters? The ECI-2 might be broken?

Thank you for your time.

Just replace the HDD with a external cheap Sata SSD. Shouldn't require that much power from the USB 2 port .

Thank you Snoopy.
In the mean time I already tried an external SSD and it worked. I also used an ifi defender+ and it eliminated the parasite sound.
