4. Operating Modes
PC Transfer Mode
In PC Transfer mode, the docking station acts as an external drive enclosure, allowing you to read, write, and expand storage directly through your computer.
- Ensure the CLONE/PC switch on the back of the docking station is set to "PC" mode.
- Connect the USB data cable from the docking station to your computer's USB port.
- Insert your HDD/SSD into the docking station. The drive(s) should be recognized by your operating system.
- You can now access the drive(s) like any other external storage device for data transfer, backup, or expansion.

Offline Clone Function
The offline clone function allows you to duplicate a source hard drive to a target hard drive without needing a computer connection.
- Disconnect the docking station from your PC.
- Insert the source disk (Disk A) into the "Source" bay (usually the top bay).
- Insert the target disk (Disk B) into the "Target" bay (usually the bottom bay).
- Important: The capacity of the target disk (Disk B) must be larger than or equal to the source disk (Disk A). The offline clone will erase all data from the target disk, so ensure you have backed up any important data from the target disk before proceeding.
- Ensure the CLONE/PC switch on the back of the docking station is set to "CLONE" mode.
- Press and hold the "START" button for 3-5 seconds until all indicator lights are on and you hear a long beep. This signifies the cloning process has begun.
- The progress indicator LEDs (25%, 50%, 75%, 100%) will light up sequentially to show the cloning progress.
- Once the cloning is complete, three long beep sounds will be heard, and all indicator lights will remain solid.
- Turn off the power and safely remove the disks.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the docking station. Avoid using liquid cleaners or abrasive materials.
- Dust Protection: The integrated dust shield helps protect the SATA interface. Keep the slots covered when not in use to prevent dust accumulation.
- Stable Environment: Place the docking station on a stable, flat surface. The rubber pads help reduce friction and vibration, ensuring stable operation of the hard drives.
- Auto Sleep Mode: The device features a 10-minute auto-sleep mode for energy saving when not in use. This also helps prolong the lifespan of the hard drives.
- Storage: When not in use for extended periods, disconnect the power adapter and store the docking station in a cool, dry place.

6. Troubleshooting
- Device Not Recognized:
- Ensure the USB data cable is properly connected to both the docking station and your computer. Try a different USB port.
- Check if the power adapter is securely connected and the power LED indicator is on.
- Verify the CLONE/PC switch is set to "PC" mode.
- Ensure your hard drive(s) are properly formatted. If not, they may need to be initialized and formatted through Disk Management (Windows) or Disk Utility (Mac).
- Try reconnecting with another USB 3.0 or USB 2.0 cable if available.
- Try a different 12V power adapter if possible.
- Offline Clone Fails or Data Loss:
- Ensure the target disk's capacity is larger than or equal to the source disk's capacity.
- Confirm the CLONE/PC switch is set to "CLONE" mode before starting the clone.
- Do not turn off the power or remove disks during the cloning process.
- Ensure both disks are correctly placed in their respective bays (Source and Target).
- The offline clone will erase all data on the target disk. Always back up critical data from the target disk before initiating a clone.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0 or USB 3.2 Gen 1 port on your computer for optimal speeds.
- Verify that UASP (USB Attached SCSI Protocol) is enabled on your system (usually automatic with compatible hardware/OS).
- Check the health and speed of your hard drive(s). Older or failing drives may limit transfer speeds.
