Thanks , appreciate the input . The owner didn ' t have the headbolts replaced , it would cost around 5 k to have them done preventatively at this point I ' m going to look at a 2012 instead . <| sep |> Got one just now , fingers crossed that it doesn ' t get cancelled ! <| sep |> I want one ! ! I ' d like a message about your day and things you most liked about it ! <| sep |> It ' s only a hunch but I still think your issue is with the UUID of the upgraded data disk . Even though the parity was rebuilt , there ' s still info in the . content files re UUIDs . Unless those weren ' t rebuilt , too ? In fact , if not , a scrub p new wouldn ' t necessarily be 100 , either . I assume you did a sync before the scrub ? gl with the memtest always good to rule out stuff like that though I suspect your hardware is fine .
