Thanks for the reply!
Firstly, my PC is a home-built system running on ASUS mobo running on Windows 10 Pro. There are 2 sets of USB ports, the USB 2.0 and USB 3.0 ports. The Wireless Pro (3TB) always works on the USB 2.0 ports (plug it in, and the computer detects the hard disk almost instantly). However, when using on the USB 3.0 ports, the hard disk led (not the battery leds) will remain lighted, and there's no sign of the computer detecting it. I can leave the Wireless Pro plugged into the USB 3.0 ports for more than an hour and there's still no detection.
Upon contacting the WD support, I was advised to install the WD SES driver.I proceeded to install the driver, rebooted the PC, and the connection using USB 3.0 works. But on subsequent PC boot ups, the computer failed to detect the Wireless Pro hard disk again. I'm baffled.
I've used the same USB 3.0 port to connect to my other WD portable hard disk (also with USB 3.0 port on the portable hard disk), the computer detects it. ..
