Windows 10 doesn't power off two USB external HDD's.

[MOS_6502]

Hello.

In the past, when I used the "Safely Remove Hardware" option in Windows 7, the OS sent the message to two Seagate Expansion drives, (2 TB, USB 3.0) stopped spinning and parked their heads; in Windows 10 the only thing that does that option is show the message of safe removal and that's it; the HDD's are still spinning and I can't hear the heads parking.

The difference from W7 to W10 is that now I use a USB HUB (powered, USB 3.0), and before, I was connecting the drives to two independent USB 3.0 ports; I suspect that the HUB have something to do with this problem.

Someone knows something about this?.

Regards.

Step 1 would seem to be to skp the hub, testing behavior of each drive without any interfering devices..

USB hubs, external powered ones specifically (that require a wall power adapter), can have a mind of their own and throw off the built in power management that controls the external drive. You can try this however:

• 
  ->Press Windows key + R on your keyboard, type devmgmt.msc, and then hit Enter.
  ->Expand Universal Serial Bus controllers.
  ->Right-click the USB Hub, and then choose Properties.
  ->Click Power Management tab, and then enable Allow the computer to turn off this device to save power option.

If that doesn't work, then it's the hub ignoring Windows command and doing it's own thing. This is why I never have my external drives connected to a hub. If I'm running out of motherboard/case USB ports, I start prioritizing what are the most important that need direct PC plug ins. I do the same with Playstation 4 which only has two USB ports. Yep, the external drive gets one, the powered hub gets the other.

Hello, thanks for the answers.

I've tried using individual USB 3.0 ports, now the heads park, but the disks keep spining and the leds are on, but if I power off the system on this state the discs stop spinning and the leds power off, strange. Perhaps something related to power settings on the BIOS?

I found this in the device manager:

Disk Drives:
Seagate Expansion Desk SCSI Disk Device
Seagate Expansion Desk USB Device

Storage controllers:
USB Attached SCSI (UAS)

Universal Serial Bus controllers:
USB Storage Device


One of the drives aren't recognised as a USB device: although both are the same model, I've purchased one in 2013 and the other in 2014.
I suppose that the one recognised as a SCSI drive is the 2013's model, so, I can't set that policy on one of them; it seems to have no effect on the model listed as a USB drive, because now the heads park (when I connect them to individual USB 3.0 ports), but the disks keep spinning and the leds are on until I power off the system.
