Hello friends, As most of you have seen the last few days, I have been posting in reference to finding a solution with power calibration errors. I bought a brand new i/o magic dual format dual layer 16x burner. It came with Nero six. I installed it and did everything right. I started up Nero and it would create an iso image, but as soon as it would try to burn, I would get the dreaded power calibration error message. Well, after posting here, several of ya advised that the media I was using was cheap. Well, in all honesty, you're right. I use compusa brand crap. Anyhow, I didn't waste my time buying new media. I called tech support for i/o magic and that was a total waste. They confirmed that everything I have was good including the adaptec aspi using nero tools and could only come up with telling me to update my motherboards ide, chipset or inkf. Then responded, if that doesn't do it, well the drive is bad. Well, I called manufacture of motherboard ABIT and with their help, I did that. Great!! I rebooted pc and tried to burn and still ended up with power calibration error. Well, I was doing research and found a post suggesting the following. I figured I had nothing to lose other than go out and buy another drive which I wasn't about to do. Anyhow, I did this and BANG!! Nero burned my CHEAP COMPUSA MEDIA LIKE CANDY. It is not the media folks. Anyhow, here it is and best of luck. It worked for me, it could work for you. Give it a shot. It's better than opening your drive to clean lense...glad I didn't listen to that option. Here it is: This might be some help to all you guys out there which are having problems with this power calibration error.what i know is that the cd burning engine which comes with xp was developed by adaptec (i might be wrong so please dont hold me to it).so heres what to do and most of your problems hopefully will be solved.this is the easiest way to tell everyone. 1 on desktop click start 2 select control panel 3 click on administrative tools 4 click on services 5 browse your way down to IMAPI CD BURNING COM SERVICE 6 right click (on IMAPI) then select properties 7 in the middle of the window it will say start up type.click on the arrow to the right and select disabled. 8 make sure you click APPLY thats it folks.you should notice that nero starts alot faster aswell please leave any feedback here just to see if it worked for you or not. hopefully it will thanks matt3678 I Thank matt3678 over at GIDForums for coming through.
