Setup
- Connect Power: Connect the provided 12V/3A power adapter to the DC-12V port on the back of the docking station and then plug it into a power outlet. The power LED will illuminate.
- Insert Hard Drives: Gently insert your 2.5-inch or 3.5-inch SATA HDD/SSD into the drive slots (Slot A and Slot B) until they are securely seated. Ensure the SATA connectors align correctly.
- Connect to Computer (for Data Transfer): If you intend to use the docking station for data transfer, connect the USB 3.0 cable from the Micro USB 3.0 port on the docking station to an available USB 3.0 port on your computer.

Operating Instructions
A. Data Transfer Mode
- Ensure the docking station is powered on and connected to your computer via the USB 3.0 cable.
- Insert the SATA HDD/SSD into the desired slot(s).
- Your computer's operating system should automatically detect the drives. You may need to initialize and format new drives via Disk Management (Windows) or Disk Utility (macOS) before use.
- Access the drives as external storage devices to transfer files.

B. Offline Cloning Mode
The offline cloning function allows you to duplicate a source hard drive to a target hard drive without a computer connection. Warning: All data on the target disk will be erased during the cloning process. Ensure you have backed up any important data from the target disk before proceeding.
- Disconnect from Computer: Ensure the USB cable is disconnected from the docking station and your computer. The docking station should only be connected to its power adapter.
- Insert Source Disk: Insert the Source Disk (the disk you want to copy FROM) into Slot A (Source).
- Insert Target Disk: Insert the Target Disk (the disk you want to copy TO) into Slot B (Target). The Target Disk must have a capacity equal to or greater than the Source Disk.
- Initiate Cloning: Press and hold the 'Clone' button (usually located on the back or top panel) for approximately 3-5 seconds until the cloning progress LEDs begin to flash.
- Monitor Progress: The LED indicators (e.g., 25%, 50%, 75%, 100%) will illuminate sequentially to show the cloning progress. When all LEDs are solid, the cloning process is complete.
- Completion: Once cloning is complete, power off the docking station and safely remove the drives.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the docking station. Do not use liquid cleaners or solvents.
- Storage: Store the docking station in a cool, dry place away from direct sunlight and extreme temperatures.
- Drive Handling: Always handle hard drives with care. Avoid dropping or subjecting them to physical shock.
- Safe Removal: When connected to a computer, always use the 'Safely Remove Hardware' option (Windows) or 'Eject' function (macOS) before disconnecting the USB cable or powering off the docking station to prevent data corruption.
Troubleshooting
- Drive Not Recognized:
- Ensure the power adapter is securely connected and the docking station is powered on.
- Verify the USB 3.0 cable is firmly connected to both the docking station and your computer.
- Check if the hard drive is properly seated in the slot.
- For new drives, ensure they are initialized and formatted in your operating system's disk management utility.
- Try connecting the docking station to a different USB port on your computer or a different computer.
- Cloning Fails or Does Not Start:
- Ensure the USB cable is disconnected from the computer during offline cloning.
- Verify the Source Disk is in Slot A and the Target Disk is in Slot B.
- Confirm the Target Disk's capacity is equal to or greater than the Source Disk's capacity.
- Ensure both drives are securely inserted.
- Try powering off and on the docking station before initiating cloning.
- Slow Data Transfer Speed:
- Ensure you are connected to a USB 3.0 port on your computer. USB 2.0 ports will operate at slower speeds.
- Verify your operating system and drivers support UASP.
- The speed of the hard drive itself can be a limiting factor.
