I'm pulling my hair out...I just got a new Liteon ihas422 using f/w 4L12 and it will not read TDK DVD+R media with media id code Ritek F16.
If the media has a complete burn on it (movie for example) it will read and play, but if it is simply blank media it just continues to try and register and tends to lock up My Computer and will never register as having blank media installed.
I've tried numerous other DVD manufacturers (office depot brand, ativa, maxell) all work. However, none of them use the Ritek F16 media code even though some are Ritek branded (just not F16).
I've tried downgrading f/w to 4L11 and even went up to patched f/w 4L16 as found on this site.
Any help would be appreciated guys, thanks.
It recognized the media finally but it took a looong time.
Sorry, not fixed, it reads media as +RW, GEEZ, WTF??
