Handling, service & preservation
- Keep the jumper setting, label, firmware, and host geometry documented. Check media read health and preserve a verified copy before migrating an old installation.
- Photograph the full label, board marks, connectors, jumpers/carrier, and date/firmware codes before service; retain the exact model suffix with collection metadata.
- Never open a hard drive outside a qualified clean environment. Stop repeated power-on attempts if the unit clicks, drops offline, or develops read errors.
- Preserve source data by making independent copies and validating checksums; SMART/self-tests cannot guarantee reliability. Distinguish measured condition from manufacturer specifications.
