5. Setup Instructions
- Power Connection: Connect the provided 12V/3A power adapter to the DC 12V port on the rear of the docking station and plug it into a power outlet.
- Connect to Computer (Optional for Data Transfer): Use the supplied USB 3.0 cable to connect the USB 3.0 port on the rear of the docking station to an available USB 3.0 port on your computer.
- Insert Hard Drives: Gently insert your 2.5-inch or 3.5-inch SATA HDD/SSD into the drive bays (labeled A and B) on top of the docking station. Ensure the drives are fully seated.
- Power On: Flip the ON/OFF switch on the rear of the docking station to the "ON" position. The power LED indicator will illuminate.
- Initialize and Format New Drives: If you are using a new or unformatted SSD/HDD, it must be initialized and formatted before use. Follow these steps for Windows:

Image: Visual guide for initializing and formatting a new hard drive in Windows.
- Right-click on "This PC" and select "Manage".
- Go to "Disk Management" under "Storage".
- Locate the new disk, right-click it, and select "Initialize Disk". Choose GPT for drives larger than 2TB, or MBR for drives 2TB or smaller.
- Right-click the unallocated space on the initialized disk and select "New Simple Volume" to create a partition and format it. Follow the on-screen instructions.
Note: Always back up any existing data on a drive before formatting, as formatting will erase all data.
6. Operating Instructions
6.1. Data Transfer
Once the docking station is connected to your computer and the drives are recognized, you can access them like any other external storage device. Drag and drop files, copy, paste, or use backup software to manage your data.

6.2. Offline Clone Function
The offline clone function allows you to duplicate a hard drive without connecting the docking station to a computer. This is useful for creating exact copies of drives.
- Ensure the power switch on the rear of the docking station is in the "OFF" position.
- 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: Ensure the memory capacity of the Target Disk (Bay B) is larger than or equal to the Source Disk (Bay A). All data on the Target Disk will be overwritten during the cloning process. Please back up any important data on the Target Disk beforehand.
- Make sure the USB cable is disconnected from any computer during the cloning process.
- Flip the power switch to the "ON" position.
- Press and hold the "Clone" button (located on the front panel) for approximately 3 seconds until the LED indicators (25%, 50%, 75%, 100%) begin to flash. This indicates the cloning process has started.
- The LED indicators will progressively illuminate to show the cloning progress: 25%, 50%, 75%, and 100%.
- When the offline clone operation is fully completed, all LED indicators will remain constantly lit.
- Once cloning is complete, turn off the docking station and remove the drives.
Note: The offline clone function cannot be processed if there are bad sectors or tracks on the hard disk.
6.3. Card Reader and USB Hub
The front panel of the docking station includes an SD card slot, a Micro SD/TF card slot, and two USB 3.0 ports. These function as a standard card reader and USB hub when the docking station is connected to a computer via the USB 3.0 cable. Simply insert your memory card or USB device into the appropriate slot/port to access its contents.
7. Maintenance
- Keep the docking station clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
- Do not try to remove your HDD or SSD device while it is active (data transfer or cloning in progress). Always eject the drive from your computer's operating system first, or turn off the docking station before removing drives.
- Ensure proper ventilation around the device during operation.
8. Troubleshooting
8.1. HDD/SSD Not Recognized by the Computer
- New or Unformatted Drive: If the HDD/SSD is new or has never been formatted, it needs to be initialized and formatted in Disk Management (refer to Section 5. Setup Instructions).
- Unallocated Space: Check Disk Management to see if there is unallocated space on the hard drive. If so, create a new volume.
- USB Connection: Ensure the USB cable is securely connected to both the docking station and a functioning USB 3.0 port on your computer for optimal performance.
- Power Supply: Verify that the power adapter is correctly connected and the docking station is powered on.
- Drive Seating: Ensure the hard drive is fully and correctly seated in the docking station bay.
- Driver Issues: While typically plug-and-play, ensure your operating system's USB drivers are up to date.
8.2. Offline Clone Fails or Does Not Start
- USB Cable Disconnected: Ensure the USB cable is completely disconnected from the computer before attempting an offline clone.
- Target Disk Capacity: Verify that the target disk (Bay B) has a capacity equal to or larger than the source disk (Bay A).
- Bad Sectors: The offline clone function cannot proceed if there are bad sectors or tracks on either the source or target hard disk.
- Power Cycle: Turn off the docking station, remove both drives, reinsert them, and try the cloning process again.
8.3. Slow Transfer Speeds
- USB Port: Connect the docking station to a USB 3.0 port on your computer. USB 2.0 ports will result in significantly slower speeds.
- UASP Support: Ensure your computer's host controller and operating system support UASP for optimal performance.
- Drive Speed: The actual transfer speed is limited by the speed of the slowest component, which is often the hard drive itself. SSDs will generally provide faster speeds than HDDs.
- System Load: High CPU usage or other background processes on your computer can affect transfer speeds.
