I have a HP 630c DVDRW drive, I checked it out and it’s a BenQ 1620 rebadge.
In the last two days, the tray has been acting weird, where when I eject, it doesn’t come all the way out, then after a slight pause, it goes all the way. When I load the tray, it goes all the way in, and then pushes back out a little bit.
Obviously, in this state, it wont read any discs. If there is a disc in the drive, it makes some totally horrible noises.
