Media and host notes
- DVD-RAM is a rewritable random-access format, but only versions and cartridge types listed for the exact unit should be used; physical cartridge compatibility is not inferred from the DVD-RAM logo.
- For DVD-RAM drag-and-drop or packet-written use, confirm host UDF/filesystem and application support. A drive that can write DVD-RAM does not guarantee operating-system mounting or packet writing.
- Internal 5.25-inch half-height SATA drive. Needs a SATA host controller, SATA data/power cables and BIOS/OS driver support. Use a compatible optical-disc application; DVD-RAM packet-writing and UDF support are host software/filesystem requirements, not guaranteed by the SATA link.
- Record drive label, firmware, controller, OS, software, disc version, write mode and verification result with each preservation image; retain checksums and error logs.
Protect recordable discs from heat, sunlight, scratches and contamination. Handle by the edge or hub and store in a case. Test each media batch before relying on it as the sole copy.
