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. CDs and DVDs are not like regular hard drives or flash drives, where you can easily delete files and free up space. Instead, CDs and DVDs are write-once media, which means that once data is written onto them, it cannot be erased or modified.

Understanding CD and DVD
CDs and DVDs are types of optical media that are used to store data, such as music, videos, documents, and software programs. The main difference between the two is the amount of data they can hold. CDs can hold up to 700MB of data, while DVDs can hold up to 4.7GB of data.
Why is it important to erase data permanently?
It is crucial to erase data from a CD or DVD permanently to ensure that sensitive data does not fall into the wrong hands. When you delete data from a CD or DVD, the data is not really gone. It is still present on the disc, but it is not visible to the user. Anyone with the right tools and knowledge can recover the deleted data easily.

Using Command Prompt
The third method to erase data from a CD or DVD is to use the Command Prompt. This method is recommended for advanced users only. To do this, insert the CD or DVD into your computer’s CD/DVD drive, and then open the Command Prompt. Type the following command: format X: /fs:UDF /q /v:LABEL, where X is the drive letter of the CD/DVD drive, and LABEL is the label you want to give the disc. Press Enter to start the formatting process.
