libCDio from GNU

offers (at least one) tool that can query (report) stats status state of optical media (CD-Rs, DVD+Rs)

libcdio-utils: sample applications based on the CDIO libraries

    This package contains a collection of small libcdio-based tools:
     * cd-drive show CD-ROM drive characteristics
     * cd-info show information about a CD or CD-image
     * cd-paranoia an audio CD ripper
     * cd-read read information from a CD or CD-image
     * cdda-player a simple curses-based audio CD player
     * iso-info show information about an ISO 9660 image
     * iso-read read portions of an ISO 9660 image
     * mmc-tool issue low-level commands to a CD drive


which, in turn [1]

cd-info may need --dvd switch for DVD R media, of course. (never cd-rs, I assume)

others include

cdrwtool -d -i


cdrecord ... -minfo , -msinfo , -toc switches (and maybe -atip)

cdrdao disk-info and cdrdao msinfo


xorriso -devices

xorriso -indev /dev/sr0 -pvd_info

"pvd" stands for Primary Volume Descriptor, which reports information (metadata) about the ISO 9660 filesystem volume (contents of the data track). (the beginning/top thereof)

xorriso -indev /dev/sr0 -toc

"toc" is Table of Contents, which is overhead for teh disc, as a whole, (equivalent to a partition table) -- point: information (data) about the sessions (and tracks) on the disc.



ImgBurn has Read and Verify modes. It gives details stats figures

except what Windows Explorer gives (which corresponds to cdrecord -minfo (msinfo mode too?) for "Free:" free/unallocated space (capacity)

see /generate-optical-filesystems (ISO9660 and its optional extensions like Joliet and Rockridge and UDF)
