My computer won't read any Sims 2 or SimCity Societies disks what should I do?

First, check if the disks are clean and free of scratches; gently wipe them with a soft cloth if needed. Ensure your computer's disk drive is functioning properly by testing it with other disks. If the problem persists, consider updating your disk drive's firmware or drivers. Lastly, you might explore using a digital version of the games through platforms like Origin or Steam.
