You're welcome. If you are protecting data, using your burning program's verify function is likely the most important quality scan you will need. As Vroom wisely pointed out, we don't know yet how well CdSpeed quality scans will correlate to longevity or data security. We're in new territory here. If you choose the LG, do look into speedpatching the firmware with MCSE to take advantage of it's 10X read capabilities. Very nice to help speed up the read/verify, TRT, and or Scandisc process and make it much more tolerable. Zips through a BD-R SL in 12 minutes.
