- Contenitore non rilevato:
- Assicurarsi che l'adattatore di alimentazione sia collegato saldamente e che l'alloggiamento sia acceso.
- Verificare che il cavo USB sia collegato correttamente sia all'alloggiamento che al computer.
- Prova una porta USB diversa sul tuo computer.
- Provare con un cavo USB diverso.
- Ensure the drives are correctly installed and secured in their trays.
- Drives not appearing in OS:
- For new drives, they may need to be initialized and formatted in your operating system's Disk Management (Windows) or Disk Utility (macOS).
- Check if the drives are functioning correctly by testing them in another enclosure or directly connecting them to a computer, if possible.
- Ensure the drives are properly seated in the enclosure trays.
- Velocità di trasferimento basse:
- Assicurati di essere collegato a una porta USB 3.0 del tuo computer. Le porte USB 2.0 comporteranno velocità inferiori.
- Verificare che il sistema operativo e i driver supportino UASP.
- The actual speed depends on the read/write speed of your installed drives.
- Evitare di trasferire molti piccoli filecontemporaneamente, poiché ciò può ridurre la velocità di trasferimento complessiva.

- Assicurarsi che il contenitore sia posizionato in un'area ben ventilata.
- Check that the 40mm cooling fan and vents are not blocked.
- Reduce the workload on the drives if they are under continuous heavy use.
