I have tried multiple types of CD-R/CD-RW, DVD-Rs with data on them and my IMac indicates the disks are blank. Not true. I also have not been able to successfully burn anything to any of these over the last few months. Commercially purchased software is hit or miss, it reads some and not others. Any suggestions?

Another help source (if you haven't already done so).
Go to your OS Help Menu. In the search field type dvd or cd
Click on all the troubleshooting topics & Support Articles that pertain to your issue.
You can also do the same in Disk Utility. Open same up.
At the bottom left of the window, click on the purple button w/the "?" in the middle.
This will bring up the Help Menu.
