Hey there, Russell!
I'm sorry to hear that you encounter such connectivity issues with the WD My Passport drive. Keep in mind that
it's not recommended for portable HDDs to be constantly connected to any device whatsoever, though. If you wish to keep your A/V storage device always plugged in and available to you, you should consider getting a desktop external drive which has an additional AC adapter and is suitable to be connected all the time.
You could try changing the USB cable on your portable WD My Passport. However, most external HDDs would spin down either way after 10 minutes of drive inactivity.
Hope this was helpful. Best of luck!
