![]() Pick a good brand name hub with good reviews. I would check with WD first or just experiment on your own to see how your drive behaves on a hub for a few days. However, some devices don’t like to operate on a hub and I don’t know if WD My Passport drives like hubs. You can add a USB 3.0 hub that has an AC adapter to supply power to those devices connected to it. If power is your problem, what can you do? that your computer is supplying only 500ma per port. You can look at the USB Hubs in Windows’ Device Manager but they often report erroneously. So, you are dividing the amperage among several or all USB ports in your computer.Ī WD 2TB drive requires at least 0.75 amps. However, some conform if you only draw power from one or two ports. However, some computers just don’t conform. ![]() USB 3.0 ports are supposed to supply 0.9 amps (same as 900 milliamps) of 5 volt current. USB 2.0 ports are supposed to supply 0.5 amps (same as 500 milliamps) of 5 volt current at each port. However, the total available USB output amperage differs from computer to computer. If the 2TB drive works when it is the only USB device connected then you can be pretty sure it’s a power problem. ![]() ![]() Have you tried the 2TB drive in another computer that has USB 3.0 ports? Does it work there? Or have you only tried it only connected your computer? If you only have access to your computer, do you have other USB devices plugged it? If so, disconnect all except your 2TB drive and see if it then behaves normally. It could be that your computer just does not supply enough power to its USB 3,0 ports. My guess is that the 2TB drive isn’t getting enough power. ![]()
