Host setup and preservation notes
- Verify the exact drive label, firmware, SATA data/power connection and optical-device enumeration before testing media. Old vendor OS lists describe tested software at release, not a modern support guarantee.
- Read support is not write support. Use media bearing a format the exact drive/firmware supports; distinguish BD-ROM, BD-R and BD-RE, and do not infer BDXL/UHD capability from the Blu-ray logo alone.
- For preservation reads or recordings, log drive model/firmware, host controller, OS/software, media type, checksums and read/verification errors. Keep original discs unmodified and store them in protective cases in a clean, cool, dry location.
