Do you have any concrete/verified descriptions of the firmware problems? I ran across plenty of people commenting on the problem, and my own intuition (or deduction, based on listening to the "click... click... click..." and eventually noting the escalating number of parks reported) plus the fix that worked for me strengthened this intuition. But I never saw a documented analysis let alone an admission on WD's part. (Admittedly, I may have missed one or both.)
