I am almost certain that I've seen a free software tool on the Internet
a while ago that did exactly this: it could tell whether the hard-drive
and/or the controller lie about flushing the data all the way to the
magnetic platter.
I think the technique involved yanking the power cord or hitting the
reset button (different failures, perhaps it's worth testing both) while
the software was doing some complex read/write operations with the disk.
After reboot, the same application looked at the disk and could tell
whether the data was properly flushed or not.

I can't remember the name of the software or anything, but I imagine
that a clever google search would reveal it.
