Hello everyone. I am having trouble connecting my WD My Passport 500GB external hard drive to my Surface Pro 3. It has Windows 8.1 Pro installed on it. I have tried the following: 1) Directly connecting the external HD to the SP3. 2) Using a mini-USB Y-cable and an adapter (since my external HD has a micro-USB) and connecting it to the SP3 and the battery of the SP3. 3) The same as #2 but instead of connecting it to the battery of the SP3, I connected it to my laptop. I know the problem is not with my external HD as it does work on my laptop. If anyone can provide any solutions or suggestions, that would be great. Thanks!
