HDD Enclosures, Loud with 1 PC, Quiet with the Other, Why?

[briane01876]

So, I have 2x MediaSonic ProBox HDD Enclosures with 3x hard drives in each one.

I'm not sure if the issue is with the Fans of the ProBox or the Hard Drives themselves. Something is making a fan-like noise. I'm thinking it's both.

When I have the ProBoxs hooked up to my Gigabyte Brix Mini PC, the ProBox fans or the hard drives don't run all the time. The only time the fans or the hard drives run is if they are accessed, say by clicking on one of the drives in Windows explorer, I will hear the drives spin up, and eventually the fan kicks in. And then about 10 or 20 minutes later, the drives go completely silent agian.

When I connect the ProBoxs to my Dell Latitude however, the fans and the drives are constantly running.

Why would my Brix let the drives/ProBoxs go quiet, but the Latitude always has them active?

What settings can I change in Windows 10 to fix the problem with the Latitude?

There is a setting that allows hdd to spin down when not in use.

Look at advanced power settings.

Control Panel\All Control Panel Items\Power Options\Edit Plan Settings

Turn Hard disk off after so many minutes. I set mine to 20 minutes, so after 20 minutes of no activity it spins down.
Of course I have to wait for it to spin up the next time I need to use it.

The Problem is ongoing. Both PC's Power Settings are the same. Both are set to turn off after 20 minutes and USB Suspend is Enabled.

In device manager check your usb hubs to see if the OS can turn them off to save power.
