I've seen people post similar issues in the past, but haven't yet seen a response which has worked for me.
First, my devices. I have a Lenovo Z50 laptop running Windows 10 which has two USB 2.0 and one USB 3.0 ports. I have a Surface Pro 4 also running Windows 10 and with the usual single USB 3.0 port. I also have a relatively newly purchased WD My Book 2TB external
hard drive.
The Lenovo is my main laptop. I have Bitlocker activated and have used it to encrypt the WD drive with Bitlocker too. The WD drive is set up for File History backups with the Lenovo.
My issue is that, recently, the WD has started only working with the USB 2.0 ports on the Lenovo. It doesn't work on the 3.0 ports on either the Lenovo or Pro 4. If you plug it in to either 3.0 port, the light comes on the hard drive and it spins up, but
nothing happens on either computer. You don't get the "ping" sound you normally get when you plug in a USB device, and the drive does not appear in my computer. Nothing appears in Device Manager either.
If you plug it in to either 2.0 port on the Lenovo it works fine.
As I say, this is recent. Originally it did work on the 3.0 ports.
This issue came up a few weeks ago and, following advice I found online, I tried accessing Device Manager on the Pro 4. I clicked "View > Show hidden devices" and then uninstalled all the greyed out devices which appeared under both "Disk Drives" and "Universal
Serial Bus controllers". This worked, and the drive started working with the Pro 4 3.0 port again. However, it's stopped working again now (same issue: light comes on, spins up, nothing on the Pro 4). I've tried the same fix again - uninstalling all greyed
out devices in Device Manager - but nothing's happened. Obviously I've also tried restarting the Pro 4 after uninstalling all the greyed out devices, but it still didn't work after restart. I've also tried plugging the WD power cable directly into a wall socket,
not an extension cable, to make sure it's getting enough power but that didn't do anything either.
Any suggestions? On the face of it, it can't be the hard drive or power cable as they work with the Lenovo 2.0 ports. But for this to happen on both 3.0 ports on the Lenovo and Pro 4 suggests it's an issue with the individual ports either, but something
about compatibility between the WD drive and 3.0 ports in general. But then why did it work with the 3.0 ports initially?
Confused face.
Any help much appreciated.
