Hello, how are you?
Welcome to the Microsoft community!
My name is Paloma B., I'm an independent advisor, I'm here to help you in the best possible way.
I understand that I would like to format a DVD + RW.
There are two ways to erase your DVD using Windows 10.
The first form is the one you reported not showing up, right-click on the device and then delete.
In this case, it also has an option at the top, in the Windows Explorer options bar.
Click on the disk to select it and in the top bar the "Manage" tab will appear, if it is not showing, click on the arrow in the right corner to lower the bar.
After that click on the "Tools" tab of the drive that is located under Manage, you will have the option "Erase this disc", check if this way you can erase the DVD.
I await news.
If these procedures helped you in any way, please click on "I solved my problem" and also mark as an answer, so you can help others users.
We will always be available for whatever you need!
