Never force the tray. Forcing damages the drive mechanism, disc, or both. Try these safe methods first:
Small pinhole near drive slot. Insert straightened paperclip, push gently until tray releases.
Do not eject. Wait for spin-down (30–60 sec after power cut). Forcing a spinning disc cracks it and scratches the lens.
Contact Microsoft Support or a console repair shop. Drive replacement is ~$40–60 used.
