Hello. I have windows 10, and some days ago I bought a 5TB HDD to add to my collection since the other HDDs I had was getting full. 

My PC has 2 USB3 ports and several USB 2 ports. The USB 3 Ports had 1 4tb HDD and one 2 TB HDD both USB 3 drives. When my 5tb drive arrived I unplugged the 2 TB from the USB3 and put it in some USB 2 instead. Since I did that, the 2tb drive fails to start when I start windows. If I remove the power cable from the drive and put it back, windows recognise the drive and everything work fine. 

The device can be seen in the Device Management but its stated as, 

Unknown USB device (Device Descriptor Request Failed)

In Properties-> general I get this error message which is very generic:
 

Windows has stopped this device because it has reported problems. (Code 43)


A request for the USB device descriptor failed.

In Order to fix the issue, I uninstalled the drivers of the device and let windows reinstall it. 
I tried to change USB port but again didn't help. 

Do you have any idea why this might happen and how to fix this?

Starting with Windows 8.1, USB driver stack enumeration has changed.   This is a known issue and irritating for sure.  One of the reasons is that the device reports itself as supporting a USB version greater than 2.00, but does not provide the required BOS descriptor, so when you plug your USB 3.0 device into a 2.0 plug, you get that error.

 

There are some fixes posted around the net, but they are quite involved and have potential to mess up your system.  Google around for fixing that error and decide if you want to mess with it.

Ah well, i think i fixed this problem. I plugged the HDD in all USBs and uninstalled drives for all usb ports. Now this HDD seems to boot properly again, but my brand new (10days old maybe) 5tb Seagate seems dead. The windows take too long to recognise it in Admin Console. its stated as "Healthy" and
"Raw". I lost some data, but fortunately not too much. I m running some seagate tool diagnostics but i don't have high hopes. It seems that the circuit on the external HDD is defective. The HDD itself sounds like working though.
