Compatibility and preservation
- Use a SATA-capable host and confirm that its controller, firmware, enclosure and operating system support the drive's full capacity and reported sector format. A physically fitting connector is not sufficient proof of compatibility.
- No annual workload or duty-cycle rating is stated in the cited X300 specification; do not infer NAS, RAID, or continuous-write suitability from the desktop/gaming positioning.
- Before use, confirm power connectors, mounting clearance, cooling and firmware behavior against the complete label and current manufacturer documentation. For older hosts, verify BIOS capacity limits and sector translation.
- For data recovery, avoid writes, formatting, repeated power cycles and stress tests. If the drive clicks, disconnects or reports read errors, power it down and seek qualified advice; never open it outside a clean environment.
- Keep verified checksums and multiple independent copies. An HDD must not be the sole copy of important data.
