Handling, service & preservation
- Avoid powering a loose 2.5-inch drive on a conductive surface. Preserve original partition table and capture a read-only image before attempting repairs on a vintage system disk.
- 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.
