I just got an LG Blu-ray burner from OWC, this one HERE, and so far, so good. I forgot to get some blank media first, so I haven't tried a burn yet, but I noticed a noise. Every few minutes or so, I can hear the drive make a little noise, like it's looking for a disc or something. It's just a second or so, a little "clickity-click" that is not loud, but when the room is quiet, I notice it. What is it doing, and is this normal? Anyone else with similar observations or knowledge?
