User:Fleetwoodta/optical-media stats

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

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

isoinfo
isoinfo -d -i /mnt/image/2014may7.iso


 * is like cd-info's  switch. (well a combination of that and ...)

isoinfo -f -i /mnt/image/2014may7.iso


 * to either role/mode/command (report '-d' primary volume Descriptor (info head about volume as a whole) or list (find) "-l" contents (all files and folders)) -- optionally add switches " " for Joliet and   for RockRidge extensions to / layers of the ISO 9660 volume.

others include

"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)

"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.

cdda2wav
and it's cdrkit equivalent (sister app): icedax (the incredible digital audio extractor)

Compact Disc Digital Audio -> .wav (PCM windows RIFF? container file)

audio "ripping" or extraction

apparently can give some info about even data CD-Rs (and DVD Rs too?)

switch.

Linux mount
Also try mounting the filesystem storage volume on the disc

optionally add options like "session" to choose which session (if more than one session(track) is on the disc).

The "nojliet" and "norock" mount optiosn instruct the mount command to NOT mount the RockRidge and Joliet extensions/layers to ISO9660.

ImgBurn
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)
