I haven't had it as long as any of my other drives. I bought it new in Jan. '07 and don't burn with it a lot or use it as my primary reader. I'm not giving up on it that easy - it burns too nicely for that.
It started acting up again about 5 hours after I posted, but it lasted only around 5 minutes and went back to normal for a couple of hours before I shut down. I'm wondering if it can be reacting to some new nearby wireless signal.
I also suspect the behavior could be caused by the trial version of PowerDVD8 I installed some months ago, but only just recently has begun popping up again when I insert a video DVD. I've just disabled all it's exe files to see if that will fix it. I don't want to uninstall it because I'm using it's Cyberlink decoder for HDTV display.
