Maintenance and Best Practices
- Safe Ejection: Always perform a "Safe Eject" or "Safely Remove Hardware" operation on your computer before unplugging the SSD. Never unplug the drive during active data transfers to prevent data corruption or loss.
- Heat Management: While the zinc alloy case aids in heat dissipation, prolonged heavy use may cause the drive to become warm. This is normal. Ensure adequate airflow around the device if used for extended periods.
- Firmware Updates: Periodically check the SSK official website for any available firmware updates for your SD501 model to ensure optimal performance and compatibility.
- Physical Care: Avoid dropping the SSD or exposing it to extreme temperatures or moisture. Keep the ports clean and free of debris.
Troubleshooting
| Issue | Possible Cause / Solution |
|---|---|
| SSD not recognized by device |
|
| Slow transfer speeds |
|
| Displayed capacity is less than advertised (e.g., 1862GB for 2TB on Windows) | This is due to algorithmic differences in how operating systems and manufacturers calculate storage capacity. 1GB is calculated as 1,024MB on Windows versus 1,000MB on SSDs. The full capacity is present. |
| SSD feels warm during use | This is normal, especially during heavy data transfers. The zinc alloy casing is designed to dissipate heat. If it becomes excessively hot, ensure proper ventilation. The drive has adaptive thermal balancing to protect itself. |
| Data corruption or loss | Always safely eject the SSD before disconnecting it. Avoid sudden power loss during transfers. If data loss occurs, specialized data recovery services may be required. |
