How to Erase Data On CD or DVD Permanently (2023)

In this article, we will discuss how to erase data on a CD or DVD permanently. In today’s digital era, CD and DVD storage have become a thing of the past. However, some people still use CDs or DVDs to store data. Erasing data from a CD or DVD is not as simple as deleting data from a computer.

Erasing data from a CD or DVD can be quite challenging, especially if you are not tech-savvy.
