6. Operating Modes

This image visually distinguishes between the two primary operating modes: Standalone Clone (without PC connection) and PC Mode (connected via USB 3.0).
6.1 PC Mode
In PC Mode, the docking station functions as an external multi-bay enclosure. All inserted hard drives will appear as individual drives on your computer, allowing you to access, transfer, and manage data as you would with any other external storage device.
- Ensure the USB 3.0 cable is connected to your computer.
- The PC/Clone Mode Button (4) should be in the "PC" position (usually indicated by a blue LED or label).
- The LED Indicators (3) for each active drive will light up.

6.2 Offline Clone Function
The offline clone function allows you to duplicate data from a source hard drive to up to three target hard drives without needing a computer connection. This is ideal for data backup, system migration, or mass duplication.
Important Notes Before Cloning:
- The capacity of the target drive(s) must be equal to or greater than the capacity of the source drive.
- All data on the target drive(s) will be erased during the cloning process. Please back up any important data on the target drive(s) before proceeding.
- Do not disconnect the power or drives during the cloning process. This can lead to data loss or damage to the drives.
Cloning Steps:
- Ensure the docking station is powered off and disconnected from any computer.
- Insert the Source Drive into the HDD1 bay.
- Insert the Target Drive(s) into the HDD2, HDD3, and/or HDD4 bays.
- Connect the power adapter and power on the docking station.
- Press and hold the PC/Clone Mode Button (4) for approximately 3-5 seconds until the LED indicators (3) start flashing. This confirms the cloning process has begun.
- The progress of the clone will be indicated by the flashing LEDs:
- 25% complete: HDD2 LED solid, HDD3/HDD4 LEDs flashing.
- 50% complete: HDD2/HDD3 LEDs solid, HDD4 LED flashing.
- 75% complete: HDD2/HDD3/HDD4 LEDs solid.
- 100% complete: All HDD LEDs (HDD1-HDD4) will be solid blue.
- Once all LEDs are solid blue, the cloning process is complete. You can now safely power off the docking station and remove the drives.
7. Maintenance
- Keep the docking station in a clean, dry environment away from direct sunlight, high temperatures, and humidity.
- Avoid dropping or subjecting the device to strong impacts.
- Do not disassemble the device. Any unauthorized disassembly will void the warranty.
