I bought a 712A back in the summer. I installed it in a Dell 400SC as a master to a Lite-On CDRW drive. It seemed to work fine. I originally had a Pioneer 106 that NEVER gave me a problem, but was limited to 4X.
Well, for various reasons, I decided to remove the LiteOn and install the Pioneer 106 alongside the Plextor so I'd have 2 DVD burners.
The Plextor is Master and the Pioneer is Slave. The Pioneer works fine still, but now the Plextor won't read or write at anything over 2X even when it recognizes DVD's with 12X capability. I have firmware 1.05 installed.
Can anyone tell me who I call (is it Plextor) to see if I can rma this drive and is it still under warranty. I believe I bought it from NewEgg in the USA (where I am).
