7203S - Power Calibration Failure ?!


I’ve been burning DVD’s and CD’s with my Optiarc 7203S for almost a year, only with a few glitchy dvd’s.
I just formatted into Windows Vista Ultimate + SP2 (I’ve been using XP all along), and now I can’t burn anything in Nero 9.
When I try burning an audio CD it goes to 5% in 2 seconds, then it jams. Saying Power Calibration Failure, or other types of error.

And another question… How do I make the drive stop starting up all the time; when it’s gone into “resting mode”, and I open “My Computer” it takes forever, because the drive needs to start spinning first.
