Are posts automatically reply-disabled after a certain age or is that condition manually determined by a forum moderator?
I think the reply I was referring to is inadequate (despite the OP's lack of detail and reply back) because the situation is actually more complicated than either the OP or the responder described. See my new post today about safely removing a drive for the issues as I encounter them. There's inconsistent info from WD about the Passport's drive status light, and indexing could be an "invisible" cause for unexplained disk activity.
I will PM the OP to ask if my new post helps address his issues, but if I hadn't also posted then I'd only be informing him and not anyone else with similar questions.
