With my own eyes I have only seen drives faking good status for seek "immediate" and
write "behind", never for flush. But I'm curious now:
How do people prove that a drive whose firmware we did not write has not lied about
flushing?
Do people actually write and flush and cycle power and read back?
Do people design hard drives to withstand much such usage?

P.S. My own checking balance was uncomfortably wrong once because in balancing my
books I typed an excessively creative data flow into Excel: a flow that was not upper
left to lower right. Turns out the Office 97 version was well known to give wrong
answers to some such data flows, to the point of eating even explicit refresh
requests. Microsoft suggested some obscure three-finger salute designed to mean
please take my refresh request more seriously.

I have also seen comments in this thread which imply that some drives do not
actually flush the data to the media during the flush cache command. I have never seen
this. Any drive which lies about flush cache would be disqualified.
