5. Operation
5.1. RAID Mode Configuration:
The MAIWO enclosure supports four RAID modes. Important: Back up all important data before changing RAID modes, as this process will erase all data on the drives. New drives must be initialized and formatted after setting the RAID mode.
- RAID 0 (FAST): Combines both drives into a single large volume for maximum speed. No data redundancy.
- RAID 1 (SAFE): Mirrors data across both drives for redundancy. If one drive fails, data is preserved on the other. Capacity is limited to the size of the smaller drive.
- LARGE (JBOD): Concatenates both drives into a single large volume without striping or mirroring. Drives are filled sequentially.
- NORMAL (PM): Presents each drive as an independent volume.

To change RAID mode:
- Power off the enclosure.
- Use a small tool (like a pen tip) to adjust the DIP switches on the rear panel according to the desired RAID mode diagram.
- Press and hold the "RESET" button on the rear panel.
- While holding "RESET", power on the enclosure. Continue holding "RESET" for approximately 5-10 seconds until the LED indicators change, then release.
- The new RAID mode is now set. Proceed to initialize and format the drives via your operating system.
5.2. Data Transfer:
Once the drives are recognized and formatted by your operating system, the enclosure functions like any other external storage device. You can drag and drop files, use backup software, or access the drives as network shares (if configured on your system).

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Do not use liquid cleaners or aerosols.
- Fan Maintenance: Periodically check the cooling fan for dust accumulation. If necessary, gently clean the fan blades with compressed air to ensure optimal airflow and prevent overheating.
- Firmware Updates: Check the MAIWO official website for any available firmware updates for your enclosure model. Follow the instructions provided with the update carefully.
- Safe Ejection: Always safely eject the enclosure from your operating system before disconnecting the USB cable or power to prevent data corruption.
