Use and preservation notes
- Close the tray and keep the drive level during operation; do not disconnect or remove a disc during an active write.
- Use known-good media and a conservative supported speed for archival copies. Finalize as appropriate and read back the disc; retain a checksum and log drive model, firmware, software, media ID and errors.
- Store optical media in protective cases away from heat, direct light, humidity, scratches and adhesive labels. Keep more than one verified copy.
