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. -- Florin Andrei http://florin.myip.org/
