As an update, I was just sitting here verifying a dvd, when suddenly the computer froze. I had to turn it off cold and restart it, then I took the disc out, and I never saw anything like it. There were several different rings, like it had stopped during burning, and continued again somewhere else on the disc. But burning had been completed, and it had moved on to verification. Only a third of the disc was burned, and this was supposed to be a full disc. Also, when you look at the disc, there is a "notch" of unburned material in one of the rings, just fading out, like if you could just take a cloth and rub the rings out.
When the computer restarted, it said "found new hardware", and the hardware may not function properly if I do not restart. So I restarted again, and now it seems to be burning again, but I no longer trust this drive. It is brand new from Newegg (OEM). I guess I have to buy a new drive now, as I'm just starting to build my new computer this week, and I do not want this drive in there now, it's acting too flaky.
