As mciahel has pointed out, if the drive you have is the TSSTcorp (Samsung) drive, that is NOT the same as the drive with the part number 17G141121103; that part number belongs to a Matshita (Panasonic) UJ-850U. Whatever Windows tells you is the drive you have; if Windows tells you that you have the TSSTcorp drive, you have that drive. If Windows tells you that you have the Matshita drive, that's what you have. Computer manufacturers tend to use multiple sources for parts, so not everyone gets the same model optical drive or hard drive (though the Asus part number may be the same, since they serve the same purpose).
Installing software for virtual drives cannot change your firmware. As long as you have not tried to flash any different firmware to the physical optical drive, you do not have to do anything dealing with firmware whatsoever.
What software did you install to create the virtual drives?
