I have tried all of that. That forum is actually for a Windows 7 OS, not the 8.1 OS that I’m using. However, there is a similar article on the 8/8.1 forum that says the same thing. That’s the first avenue of approach that I took, then I contacted support for my computer and they uninstalled and then reinstalled all of my USB ports. And, it happened again. What I’m trying to find out is if there’s a compatability problem with the 8.1 OS and Western Digital external hard drives.
