3. Setup Instructions
- Power Connection: Connect the provided DC 12V/3A power adapter to the DC 12V port on the rear of the docking station. Plug the adapter into a power outlet.
- USB Connection: Connect the provided USB 3.0 Type-A cable from the USB 3.0 port on the rear of the docking station to an available USB 3.0 port on your computer.
- Insert Drives: Ensure the docking station is powered off. Gently insert your 2.5-inch or 3.5-inch SATA HDDs/SSDs into the drive bays (Slot A and Slot B) until they are securely seated.
- Power On: Flip the ON/OFF switch on the rear of the docking station to the 'ON' position. The power indicator LED will illuminate.
4. Operating Instructions
4.1. Data Transfer Mode
When connected to a computer via USB, the docking station functions as an external drive enclosure and card reader. Insert your SATA drives into the bays and connect the device to your computer. The drives will appear as removable storage, allowing you to transfer files directly.

4.2. Offline Cloning Function
The offline cloning function allows you to duplicate a hard drive without connecting to a computer. This process copies all data from a source disk (Slot A) to a target disk (Slot B).
Important Considerations:
- Cloning only supports copying from Slot A (Source Disk) to Slot B (Target Disk).
- The capacity of the target disk (Slot B) must be equal to or greater than the capacity of the source disk (Slot A).
- Ensure both disks are free of bad sectors for a successful clone.
- All data on the target disk (Slot B) will be overwritten during the cloning process. Back up any important data from the target disk before proceeding.

Cloning Method Steps:
- Prepare Disks: Ensure the docking station is powered off. Insert the source disk into Slot A and the target disk into Slot B.
- Power On: Connect the power adapter and turn on the docking station using the ON/OFF switch. Wait 3-5 seconds for the device to initialize.
- Initiate Cloning: Press and hold the OTC/OTB button on the rear panel for 3 to 5 seconds. The 25%, 50%, 75%, and 100% progress indicators will flash simultaneously.
- Confirm Cloning: Release the OTC/OTB button, then press it again within 3 seconds to confirm and start the cloning process.
- Monitor Progress: The cloning progress will be indicated by the LEDs:
- The 25% indicator will flash. Once 25% is complete, it will remain solid.
- The 50% indicator will then flash. Once 50% is complete, it will remain solid.
- This sequence continues for 75% and 100%.
- Power Off: Once cloning is complete, turn off the docking station and remove the drives.
4.3. Card Reader Functionality
Insert SD or TF cards into their respective slots on the front panel. When connected to a computer, these cards will appear as separate removable drives, allowing for direct file access and transfer.

8. Troubleshooting
Common Issues and Solutions:
- Device not recognized by computer:
- Ensure the USB cable is securely connected to both the docking station and the computer.
- Verify the docking station is powered on.
- Try connecting to a different USB port on your computer.
- Test with a different USB cable if available.
- Hard drive not detected:
- Ensure the hard drive is properly seated in the bay.
- Check if the hard drive is functional by testing it in another device.
- For new drives, they may need to be initialized and formatted in Disk Management (Windows) or Disk Utility (Mac OS) before use.
- Offline cloning fails or target disk not visible after cloning:
- Verify that the target disk's capacity is equal to or greater than the source disk's capacity.
- Ensure there are no bad sectors on either disk.
- Follow the cloning steps precisely, especially the timing for pressing the OTC/OTB button.
- If the target disk is not visible after cloning, connect it to a computer, open Disk Management (Windows) or Disk Utility (Mac OS), and ensure the disk is set to 'Online' status. You may need to assign a drive letter.
- Slow data transfer speeds:
- Ensure you are connected to a USB 3.0 port on your computer.
- Verify that your operating system and drivers support UASP.
- The actual speed may vary depending on the hard drive's performance and system configuration.
