Blank disc status for CD-ROM (udiskie)?
 

I have a project where, on CentOS/RHEL6, I checked the cd-rom to ensure a blank disc was inserted in the CD-ROM tray. I used 'udisks --show-info /dev/sr0' to accomplish this.

Since CentOS7 has a front-end called udiskie, I cannot get that same information unless I use the "monitor" option to udiskie. This option however does not end or return a status. You must Cntl-C out to quit it, but you can clearly see the message that a blank disc was inserted.

How can I obtain the correct "blank" status on CentOS7? I've tried many of the other options using udiskie and udisks itself does not seem to be available at the command line.

Thanks,

Hi,

There should be a dvd+rw-tools package available, which contains the "dvd+rw-mediainfo" command. I've used this in the past, by looking at the media type in its output. It might provide what you are looking for.
