I experienced drives spinning back up after they had been flushed on powerdown, which is not necessarily wrong, (I.E. I never noticed any data loss), but it's not ideal. Can't we do:
* Standby * Flush * Standby
or is there a reason not to? I know there were discussions about the right order to do the standyby and flush, and as far as I remember, we never reached a conclusion :-).
