5. Operating Instructions
5.1. Connecting to a Computer
- Ensure the docking station is powered on.
- Connect the USB 3.0 cable from the docking station to your computer.
- Insert your SATA hard drives or SSDs into the HDD1 and/or HDD2 slots.
- The drives will be recognized by your operating system as external storage devices. You can now access, read, and write data to them.
5.2. Standalone Clone Function (Disk Duplication)
This function allows you to clone a source hard drive (HDD1) to a target hard drive (HDD2) without connecting to a computer.
- Disconnect from PC: Ensure the docking station is NOT connected to any computer via USB.
- Insert Drives: Insert the source drive into the HDD1 slot and the target drive into the HDD2 slot. The target drive (HDD2) must have an equal or larger capacity than the source drive (HDD1).
- Power On: Connect the power adapter and turn on the docking station.
- Initiate Clone: Press and hold the 'Clone' button (often labeled 'Clone/Erase') for approximately 3-5 seconds until the clone process begins. The LED indicators (25%, 50%, 75%, 100%) will illuminate sequentially to show progress.
- Monitor Progress: Do not interrupt the cloning process. When the 100% LED remains solid, the cloning is complete.
- Remove Drives: Power off the docking station before safely removing the hard drives.

5.3. Erase Function (Secure Data Deletion)
This function securely overwrites all data on a hard drive.
- Disconnect from PC: Ensure the docking station is NOT connected to any computer via USB.
- Insert Drive: Insert the hard drive you wish to erase into either the HDD1 or HDD2 slot.
- Power On: Connect the power adapter and turn on the docking station.
- Initiate Erase: Press and hold the 'Erase' button (often combined with 'Clone/Erase') for an extended period, typically 5-10 seconds, until the erase process begins. The LED indicators will show progress.
- Monitor Progress: Do not interrupt the erasing process. All data on the drive will be securely overwritten.
- Remove Drive: Power off the docking station before safely removing the hard drive.

6. Maintenance
- Keep the docking station clean by wiping it with a soft, dry cloth.
- Do not use liquid cleaners or solvents.
- Ensure the ventilation openings are not blocked to prevent overheating.
- Store the device in a cool, dry place when not in use.
7. Troubleshooting
- Device not powering on: Check if the power adapter is securely connected to both the docking station and the wall outlet. Try a different power outlet.
- Hard drive not detected by PC:
- Ensure the USB 3.0 cable is firmly connected to both the docking station and the computer.
- Try connecting to a different USB port on your computer.
- Verify that the hard drive is properly seated in the docking station slot.
- Check Disk Management (Windows) or Disk Utility (macOS) to see if the drive is recognized but uninitialized or unformatted.
- Clone function fails or stops:
- Ensure the target drive (HDD2) has an equal or larger capacity than the source drive (HDD1).
- Verify that the docking station is NOT connected to a computer via USB during the cloning process.
- Check both source and target drives for physical damage or errors.
- Slow data transfer speeds: Ensure you are connected to a USB 3.0 port on your computer. Older USB 2.0 ports will result in slower speeds.
