Well the All Write was not alright. Would not load factory CDDA or DVD-RAM. Latest QP5B firmware. Would write and play DVD -R +R R/W and lightscribe just fine. Since this drive is only a couple months old it left me scratching my head. I had an epiphany, reload the firmware even though the utility complained I'm loading the same version. Make backup first, reload QP5B. Reboot and VOILA! the All Write is alright!
No explanation other than corrupted firmware but I have done nothing to corrupt it. I'm not a firmware hacker nor do I bother with third party utilities other than to backup existing firmware.
Just an FYI
