Nero is definitely not my choice of disk compilation utility, however, it is without a doubt one of the most popular disc burning software and therefore you might land-up on some disc-image file compiled in "Nero Image" format (.nrg file). Thankfully, .nrg files can be easily converted to standard .ISO file-format which is supported by all disc burning utilities, nrg2iso does exactly that by converting Nero CD images to ISO-9660 CD images with a single click almost instantly.

If your CD/DVD burner is making coasters failing to write CD's and DVD's, throwing a "Power Calibration Error" or "Medium Speed Error", here are a few solutions you should try.

Their could be several possible reasons and solutions for the above error, basically what is happening is for some reason the CD/DVD burning software is unable to determine the Optimum Power Calibration rate (a small pre-burn test to determine optimal laser power for writing), resulting a disk burn failure. There is no easy way to pinpoint the exact reason, so try all the possible fixes from top to bottom (easy to hard) and see what works:

• Try using different brands of quality blank media, most common reason for such error's is cheap blank media.




• Try burning at lower speeds (Highly effective).




• Disable IMAPI Service (Work's in most cases):
1. Launch Control Panel -> Administrative Tools -> Services .
2. Browse for "IMAPI CD-Burning COM Service", Right-click on it and select properties.
3. Change Startup Type to Disabled.

4. Click Apply and Reboot.
