Force Optical Power Calibration before burn is turned on in the preferences

Question

I was able to burn cds until I updated to version 7. Now it looks as though it is burning, but when you eject the cd, all files disappear! I want to turn the above mentioned preference off, so I can try slowing down the drive speed. However, I can not find where to do so. I searched the registry and looked in the program files to see where the option is being stored, but I was unsuccessful. Please advise.

Answer 1

This is the current info. Its wierd, after I burn and leave the cd in the drive, I could run a diagnostic and it will say there are files on the cd and no error reported. After I eject and re-read -- the disc is empty, but still no error thrown.

If you have multiple drives on the same IDE or SCSI bus, these drives may interfere with each other.
Some computers need an update to the ATA or IDE bus driver, or Intel chipset. If iTunes has problems recognizing CDs or hanging or crashing while importing or burning CDs, check the support site for the manufacturer of your computer or motherboard.
