I just upgraded my Cendyne Lightening III (Verbatim) to LTR 40125S firmware ZS0A last week. And right now, I just upgraded to firmware ZS0J.
Using Nero info tool, my Liteon LTR 40125S has Mt. Ranier support!
I have a screen capture of the Nero tool but I couldn't figure out how to attach it to this message.
See for yourself once you upgrade.
This is cool.
