How to detect current media type in CLI under Windows? (DVD-RW, BD-R, etc)

I've tried with wmic cdrom get /format:list but no info about the current media type.

I want to detect if the disc is a CD, DVD, BD, RW, DL... etc. In Windows GUI under Computer we can see the information according to the icon displayed for the optical drive.

Also, I can't find the meaning of the Availability and the Capabilities values, if you know a document talking about it, it would be great.

C:\>wmic cdrom get /format:lis

I want to detect if the disc is a CD, DVD, BD, RW, DL... etc. In Windows GUI under Computer we can see the information according to the icon displayed for the optical drive.

You have the right command, the information you seek is under the "Caption" field.

So for:

wmic cdrom get /format:list

In your example, in the Caption field you can see it is a BD-RE (blu-ray Recordable

Caption=HL-DT-ST BD-RE BH12LS35

For your second question:

Also, I can't find the meaning of the Availability and the Capabilities values, if you know a document talking about it, it would be great.

The descriptions and everything related to this class are found on MSDN here:

The Availability is what the media is capable of, and Capability is what your drive is capable of. So:

Availability=3
Capabilities={3,4,7}
CapabilityDescriptions={"Random Access"," Supports writing"," Supports Removable Media"}

This would mean that your current media supports reading only, but not writing. The "supports removable media" probably doesn't mean anything useful. Based on the Size=39621033984 parameter you have a standard DVD-R loaded. DL would be double that, and Blu-Ray more. Try experimenting with different media to see what the results are.
