May I also add my take on SmartBurn, as is concerned here:

SmartBurn is a technology LiteOn implements to do a little extra quality check BEFORE the burn, supplementing the Optimal Power Calibration that takes place before every burn done. This extra quality check will determine mainly one thing: if the drive decides to write at your requested speed or not. It is advised to leave it on when using poor media, though it will NOT fully compensate fully for foolish write speed decisions or for media that cannot be written properly by any drive.


When to DISABLE SmartBurn:

• If you have known good media, and you want to attempt to decrease your burn time by a few second [though this benefit may not mean much in the grand scheme of things].
• If you have known good quality media and are attempting to overspeed it, as SmartBurn may be a bit aggressive and not allow your attempted overspeed to take place.
• When you have good OR mediocre media specifically supported by the drive's firmware, and testing reveals that ONLY disabling SmartBurn improves write quality. Some drives will be TOO aggressive with their pre-burn calibration with SmartBurn enabled, making worse results than if the drive just used the original write strategy found in firmware.

I personally recommend testing to see how write quality is with SB on and with SB off, and decide from there.


Note that disabling it does not guarantee that your media is written at your requested speed [as there can be other physical reasons such as disc warp, etc, where the drive will have to slow down]. A reminder again that leaving it enabled will NOT fully fix any issues resulting from poor media or foolish speed choices, so make sure you still watch your write speeds, and make wise use of the HyperTuning/Online HyperTuning and OverSpeed options!
