- Connect the dual-function data cable (USB-C to USB-C or USB-C to USB-A using the adapter) from the docking station to your computer or compatible device.
- Press the power button on the back of the docking station to turn it on. The LED indicators on the front will illuminate.

5. Operating Instructions
5.1. Data Transfer Mode
Once connected to your computer and powered on, the inserted hard drives will appear as removable storage devices. You can now drag and drop files, copy, paste, and manage your data as you would with any other external drive. The USB 3.2 Gen 2 interface ensures high-speed data transfer, significantly reducing waiting times for large files.

5.2. Offline Cloning Function
The offline cloning feature allows you to duplicate a hard drive without connecting to a computer. This is ideal for creating backups or upgrading drives.
- Ensure the docking station is powered off and disconnected from your computer.
- Insert the Source Disk (the drive you want to clone FROM) into the Source Bay (usually labeled HDD1 or the first bay).
- Insert the Target Disk (the drive you want to clone TO) into the Target Bay (usually labeled HDD2 or the second bay).
- Important: The capacity of the Target Disk must be equal to or greater than the capacity of the Source Disk. Data on the Target Disk will be overwritten.
- Set the clone switch (usually on the back) to the 'Clone' or 'Offline' position.
- Connect the power cord and power on the docking station.
- Press and hold the 'START' button (usually on the back) for a few seconds until the cloning process begins. The progress indicators (LEDs) will light up, typically indicating 25%, 50%, 75%, and 100% completion.
- Once all progress LEDs are solid, the cloning process is complete. Power off the docking station and safely remove the drives.

5.3. Device Compatibility
The docking station is compatible with a wide range of devices and operating systems, offering flexible usage scenarios.

- Compatible Devices: PCs, Laptops, Smartphones, Tablets, Smart TVs, Projectors, Smart Routers, Gaming Consoles (e.g., PS4), Digital Cameras.
- Supported Operating Systems: Windows, Mac OS, Linux OS, iPad OS.
6. Maintenance
To ensure the longevity and optimal performance of your Yottamaster Dual Bay Hard Drive Docking Station, consider the following maintenance tips:
- Keep it Clean: Regularly wipe the exterior with a soft, dry cloth. Avoid using liquid cleaners or solvents.
- Dust Prevention: Keep the dust-proof flip-covers closed when not inserting or removing drives to prevent dust accumulation inside the bays.
- Proper Ventilation: Ensure the docking station is placed in a well-ventilated area to allow for efficient heat dissipation. Avoid blocking any ventilation openings.
- Handle with Care: Avoid dropping or subjecting the device to strong impacts.
- Power Off Safely: Always power off the docking station before disconnecting it from the power source or computer, and before removing hard drives.

7. Troubleshooting
If you encounter issues with your docking station, please refer to the following common problems and solutions:
- Drives not recognized:
- Ensure the docking station is powered on and properly connected to your computer.
- Verify that the hard drives are correctly seated in their bays.
- Check if the drives are formatted and partitioned. New drives may need initialization and formatting via Disk Management (Windows) or Disk Utility (Mac OS).
- Try connecting the docking station to a different USB port or computer.
- Ensure the drives are SATA I/II/III. IDE drives are not supported.
- Slow transfer speeds:
- Ensure you are using a USB 3.0/3.1/3.2 port on your computer. Connecting to a USB 2.0 port will result in slower speeds.
- Verify that your operating system supports UASP (USB Attached SCSI Protocol) for optimal performance.
- The actual speed may be limited by the speed of your hard drive itself.
- Offline cloning fails or does not start:
- Ensure the docking station is disconnected from any computer.
- Confirm that the Target Disk's capacity is equal to or greater than the Source Disk's capacity.
- Make sure the Source and Target disks are inserted into the correct bays.
- Press and hold the 'START' button for the required duration (typically a few seconds) until the cloning process initiates.
- Check for any error indicators (LEDs) on the device.
- Device powers off unexpectedly:
- Ensure the power adapter is securely connected to both the docking station and the power outlet.
- Avoid placing the device in direct sunlight or enclosed spaces where heat can build up.
