Drive Info

Diagnostic snapshot of attached optical burners and any currently-loaded media.

When to use

Before starting a burn job, to confirm device path and media compatibility.

Troubleshooting "why isn't my drive being detected" or "what disc is in there right now".

Inputs to gather

Optional explicit device path (/dev/sr0, etc.). Otherwise enumerate all.

Procedure

Verify user is in the cdrom group: groups | grep -q cdrom. If not, instruct sudo usermod -aG cdrom $USER && newgrp cdrom. (Read-only ops may still work without it, but burns will not.)

List drives:

wodim --devices — shows recognised burners with bus/lun and capabilities.
lsblk -o NAME,TYPE,RM,MODEL filtered to TYPE=rom.

Auto-detect default device: lsblk -nro NAME,TYPE | awk '$2=="rom"{print "/dev/"$1}' | head -1.

For each detected device (or the explicit one provided):

dvd+rw-mediainfo <device> — shows media type, capacity, blank/used status, write speeds.
Capture stderr for "no medium" cases and report cleanly as "tray empty / no disc".

Output / side effects

Stdout summary only. No files written.

Safety / constraints

Read-only; safe to run any time.
