First off, is this drive in a laptop? If so, what is the laptop's exact model? Secondly, what problem(s) are you having with the drive? Which build of Win 7 are you running? Was your installation a clean install or an upgrade?
I've done some searching and can't seem to find any firmware updates for that drive at this time (in answer to your question). I would strongly advise against using anything (drivers/firmware updates) but what the manufacturer for that drive (or the manufacturer of your laptop IF it is indeed in a laptop) has released, doing so could brick the drive.. In other words if this is in a laptop and you've checked with the manufactuer's site and see nothing in the line of driver/firmware updates, then no there aren't any available at this time..
