4. Setup and Installation
- Insert Hard Drives:
- Gently slide your 2.5" or 3.5" SATA HDD/SSD into the drive bays (A and/or B) until they are securely seated. Ensure the SATA connectors align correctly.
- For data transfer mode, you can insert one or two drives.
- For offline cloning, insert the source drive into Bay A and the target drive into Bay B.
- Connect Power:
- Connect the provided power adapter to the DC 12V input port on the rear of the docking station.
- Plug the power adapter into a wall outlet.
- Connect to Computer (for data transfer):
- Connect one end of the USB 3.0 cable to the USB 3.0 port on the rear of the docking station.
- Connect the other end of the USB 3.0 cable to an available USB 3.0 port on your computer.
- Power On:
- Press the On/Off switch on the rear panel to power on the docking station. The power LED indicator will illuminate.
5. Operating Instructions
5.1. Data Transfer Mode (Connected to Computer)
When connected to a computer via USB, the docking station functions as an external drive enclosure, allowing you to access data on the inserted HDDs/SSDs.
- Ensure the docking station is powered on and connected to your computer via the USB 3.0 cable.
- The operating system will automatically detect the drives. New drives may require initialization and formatting before use.
- Access the drives through your computer's file explorer (Windows) or Finder (macOS).

Figure 5.2: The docking station supports SATA III at 5Gbps with UASP, enabling quick access to large files.
5.2. Offline Clone Function (Stand-alone Duplication)
The offline clone function allows you to duplicate a source drive (Disk A) to a target drive (Disk B) without connecting to a computer. The target drive must have a capacity equal to or greater than the source drive.

Figure 5.3: Visual guide for the one-click HDD duplication or capacity update process, showing source disk (A) and target disk (B).
- Prepare Drives:
- Ensure the docking station is powered off and disconnected from any computer.
- Insert the Source Disk (the drive you want to copy from) into Bay A.
- Insert the Target Disk (the drive you want to copy to) into Bay B.
- Important: All data on the target disk (Bay B) will be erased during the cloning process. Back up any important data from the target disk before proceeding.
- The target disk's capacity must be equal to or larger than the source disk's capacity.
- Start Cloning:
- Power on the docking station using the On/Off switch.
- Press and hold the "Clone" button (located on the front panel) for approximately 3-5 seconds until the clone progress LEDs start flashing.
- Release the button.
- Monitor Progress:
- The LED indicators (25%, 50%, 75%, 100%) will illuminate sequentially to show the cloning progress.
- When all four LEDs are solid, the cloning process is complete.
- Finish:
- Power off the docking station.
- Carefully remove the drives.
Note: Do not disconnect the power or remove drives during the cloning process, as this may lead to data corruption.
6. LED Indicators
The LED indicators provide visual feedback on the docking station's status and cloning progress.

- Power LED: Illuminates when the docking station is powered on.
- Drive A/B Activity LEDs: Flash when data is being accessed or written to the respective drive.
- Clone Progress LEDs (25%, 50%, 75%, 100%):
- Flash sequentially during an active cloning process.
- Remain solid when the cloning process is complete.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Docking station does not power on. | No power connection or faulty power adapter. | Ensure the power adapter is securely connected to the docking station and a working power outlet. Check the On/Off switch. |
| Drive not detected by computer. | Loose drive connection, faulty USB cable, uninitialized/unformatted drive, or incompatible drive. |
|
| Offline clone fails or does not start. | Target drive capacity too small, drives not properly seated, or clone button not held long enough. |
|
| Slow data transfer speeds. | Connected to a USB 2.0 port, or drive performance limitations. |
