Followed the steps provided below by Western Digital Service and Support and seems to be working adequately so far. Keeping fingers crossed against memory leakage/creep.
Note that I was already using the latest versions of the WD firmware, the WD software, and Windows.NET, so perhaps uninstalling and reinstalling was the trick in my case. I hope so.
Be aware that anti-virus and anti-spyware should be turned off first. In your case, you might try their method of checking that Java, Flash, and .NET are current, then updating firmware, then uninstall/reinstall latest WD software. Good luck.
The last portion (Step 4, regarding the stopping and restarting of WD services may also be crucial). I went through the whole thing, just as they laid it out... and so far, so good.
Thank you for contacting Western Digital Customer Service and Support...
