I have been having problems with my drive for the last couple of weeks
now. When I first got it I could burn like crazy on ridata R04's at 16x
and things were fine. Then I started getting the no seeks and power
calibration errors. That waisted alot of disc. I tried a different brand
(maxell) and burned slower, no avail.
In the end tonight I tried a different power supply and behold I have
a perfect good quality burn (96% in nero quality scan). I replaced
a 350w case brand with a thermaltake 420W I had here all this time.
Simple fix saves quite alot of money. Here all this time I thought it was:
Drive, firmware choice, OS drivers, or media. None of the above.
Hope this info could be of some use to others looking for resolution.
