Media type detection

Hi all!

Is there any way to detect the type (CD or DVD) of the media inserted into
the DVD drive?

Thanks,

Dany

Common way to differ CD Vs. DVD is to issue READ_DVD_STRUCTURES (0xAD)
command to the drive itself. If you

want to know more - read and parse current profile retrieved with
GET_CONFIGURATION (0x46) command.

IOCTL_CDROM_GET_CONFIGURATION will report the data you require; look at
the first header’s “Current Profile” item, it’s usually “good enough”.

If it’s a DVD media type, you can also use IOCTL_SCSI_PASS_THROUGH to
send a READ DVD STRUCTURE command (subtype 0) to get physical media
info.
