I've searchd the threads, but havn't found something quite like this. Before i re-formatted Windows, i could format(CDRW), write(CDRW), whatever i wanted, with Nero 6 Ultra. I had a relatively new version. I formatted, windows was going bonkers.. I had an earlier version of Nero when i reinstalled windows, and i installed it, everything went ok. I went to format the CDRW, it gave me a power calibration. So, i read some of the threads... well, i got Nero 220.127.116.11 (latest version), and i get a power calibration error when i go to format my cd from other threads, i also 1) updated my firmware 2) updated my nero 6 version 3) went into device manager, and turned off a service.. and i still get this error. I've tried 12x, 10x, and 8x, and i still can't format. IT usually stops before it finishes, or it gets on 100% and just goes on until it times out. I can't figure this one out..
