How to use

Install 3.5‑inch hard drives into the accessible bays according to the enclosure's mechanical guides and secure them as instructed by the manufacturer. Connect the external power supply, then attach the enclosure to a computer using the USB 3.1 cable. The host operating system will detect each drive; if required, initialize, partition and format drives using the OS disk management tools before storing data. For safe removal, use the operating system's eject or safe‑remove procedures prior to disconnecting the cable or switching off the power.

Recommendations

Place the enclosure on a stable, flat surface with sufficient ventilation and keep vents clear. Use appropriate filesystem formats for your operating system and consider regular backups and monitoring of drive health when consolidating important data. Avoid moving the enclosure while drives are spinning and follow safe‑disconnect procedures to reduce the risk of data loss.
