Samsung 18x burner w/lightscribe. Had it almost a year and now, just about every time I burn a cd/dvd the tray will not open. The bunrs are always good, no errors/coasters but I have to reboot the pc to get it to open. I've already flashed it to the latest firmware but the problem still exists. I noticed newegg says that it will replace the unit within 1 yr so I am probably going to RMA it. Just never heard of a drive behaving this way. btw - I just did a lightscribe burn and it ejected fine.
