Optical-media preservation notes
Read-only drive capabilities do not establish the condition or authenticity of a disc. Preserve an untouched source, create verified images for access, and record the drive model, firmware, host software, media type and read errors.
- Handle by the edge or center hole; avoid writing or adhesive labels on the data side.
- Store discs in protective cases in a cool, dry and dark environment. Keep more than one independently verified copy of important content.
- Do not infer support for a specific recordable-media subtype from DVD-ROM support alone; follow the exact drive documentation and record test results.
Identification and host checks
- Verify the model suffix, revision, connector type and jumper setting on the physical unit; near-identical family members can differ.
- Requires PATA/IDE host support and a free 5.25-inch bay. Configure jumper and cable position per the manual. Modern adapters may not expose all ATAPI commands. Regional DVD video playback also depends on firmware state and host software.
- Separate optical reading from filesystem support, copy protection, region setting, codec availability and boot-firmware behavior; those depend on the complete host setup.
