Determining type of disc

Hi,

 

I'm trying to use cdrecord to determine the type of disc that is currently in a drive. I need to know whether or not there's a blank recordable disc available.

 

I can do something like

 

cdrecord -dev=0,1,0 -checkdrive -v

 

The only difference between a commercial DVD and a blank DVD-R is that the "Profile" entry marked "(current): is x0011 for the DVD-R and x0010 for the DVD, and no profile is marked "(current)" on an empty drive.

 

Alternatively, I can do:

 

cdrecord -dev=0,1,0 -toc

 

...but that would require a lot more creative grepping and strikes me as less reliable.

 

Is the -checkdrive approach the best way of doing it? Any suggestions gratefully received.

 

- Phil

This is not for requesting the media information but for requesting _driver_
information

Did you read the man page? Did you try to use the -minfo option?

To check the current media status, there is


cdrecord -minfo

to add verbose information on the medium, call

cdrecord -v -minfo
