I've owned my drive since last November. The drive no longer reads DVDs/DVD+-Rs, and there are two amber blinks. I've checked forums/plextor website/and manual. I've even run the diagnostics. Nothing.
A friend of mine bought it at the same time. He has the same problem. The drive is obviously not built well, which is a disappointment considering Plextor has always been about quality all these years. I guess they wanted to rush out an 8X drive, and this is the result. Other people on forums are experiencing this problem too.
I guess the only thing will be to RMA it. Wow, that's wonderful.
You might want to consider other brands if you're thinking about this one.
Thanks, and hope you have better luck than me.
