4. Setup
- Connect Power: Plug the DC 12V/3A power adapter into the DC 12V port on the back of the docking station, then plug the adapter into a power outlet.
- Connect to Computer: Connect the included USB 3.0 cable from the USB 3.0 port on the back of the docking station to an available USB 3.0 port on your computer.
- Insert Drives: Gently insert your 2.5-inch or 3.5-inch SATA HDD/SSD into the drive bays (Slot A and Slot B) until they are securely seated. Ensure the SATA connectors align correctly.
- Power On: Flip the ON/OFF switch on the rear panel to the 'ON' position. The power LED indicator on the front will illuminate.
- Driver Installation: The docking station is plug-and-play and typically does not require additional drivers for Windows, Mac OS, or Linux. Your operating system should automatically detect the connected drives.
- Initialize and Format New Drives: If you are using a brand new HDD or SSD, it may need to be initialized and formatted before it can be used.
Initializing and Formatting a New Drive (Windows)
If your SSD or HDD has never been formatted, your computer will not be able to detect it for use. Follow these steps to initialize and format the disk:

This instructional image provides a step-by-step guide for initializing and formatting a new SSD or HDD on a Windows operating system. It shows how to access Disk Management, initialize the disk as GPT or MBR, and create a new volume to make the drive usable.
- Right-click on 'This PC' (or 'My Computer') and select 'Manage'.
- In the Computer Management window, go to 'Disk Management' under 'Storage'.
- Locate your new disk (it will likely be marked as 'Unallocated' or 'Not Initialized'). Right-click on it and select 'Initialize Disk'. Choose GPT for drives larger than 2TB, or MBR for drives 2TB or smaller.
- After initialization, right-click on the 'Unallocated' space of the disk and select 'New Simple Volume'. Follow the wizard to create a new partition and format it (NTFS is recommended for Windows).
Note: Please back up any important data before formatting a drive, as formatting will erase all existing data.
5. Operating Instructions
5.1 Data Transfer
Once the drives are properly installed and detected by your computer, you can use them like any other external storage device. Simply drag and drop files, or use copy/paste functions to transfer data between your computer and the drives in the docking station, or between the two drives themselves.

This image shows the ikuai docking station in a typical usage scenario, connected to a laptop. Two hard drives are inserted into the bays, and a smartphone is connected to one of the front USB 3.0 ports, demonstrating its ability to charge devices or connect other USB peripherals.
5.2 Offline Clone Function
The offline clone function allows you to duplicate a source disk (Disk A) to a target disk (Disk B) without connecting the docking station to a computer. This is ideal for system backups or drive upgrades.

This diagram illustrates the offline cloning process of the ikuai docking station. It shows a source disk (A) being cloned to a target disk (B), with LED indicators showing cloning progress (25%, 50%, 75%, 100%). A button labeled 'OTC/OTB' is highlighted, indicating the one-touch clone feature. The target disk must be equal to or larger than the source disk.
- Ensure the docking station is powered off.
- Insert the source disk into Slot A and the target disk into Slot B.
- Important: The target disk (Slot B) must have a capacity equal to or greater than the source disk (Slot A). All data on the target disk will be erased during the cloning process.
- Press and hold the 'OTC/OTB' button on the rear panel for approximately 3-5 seconds until the cloning progress LEDs (25%, 50%, 75%, 100%) begin to flash.
- Quickly release the button, then press it again briefly to confirm the cloning process.
- The cloning process will begin, and the progress LEDs will illuminate sequentially to indicate completion percentage.
- Once all four LEDs (25%, 50%, 75%, 100%) are solid, the cloning process is complete.
- Power off the docking station before removing the drives.
5.3 Using Card Readers and USB Ports
The front-facing TF (Micro SD) and SD card slots allow direct access to memory cards. The two additional USB 3.0 ports can be used to connect other USB devices such as flash drives, external hard drives, or to charge smartphones and other compatible devices.
Note: The docking station's USB 3.0 ports and card readers may not function simultaneously with certain configurations or if the connected computer's USB controller has limitations. If you experience issues, try using one function at a time.
5.4 Automatic Sleep Mode
To conserve power and reduce wear on your hard drives, the docking station will automatically enter sleep mode after 10 minutes of data inactivity. The drives will spin down, and the activity LEDs will dim. The drives will automatically wake up when data access is requested.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the docking station. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the docking station is placed in a well-ventilated area to prevent overheating, especially during prolonged use or cloning operations.
- Safe Removal: Always safely eject or unmount drives from your operating system before powering off the docking station or physically removing the drives. This prevents data corruption.
- Storage: When not in use, store the docking station and its components in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
- Drive Not Detected:
- Ensure the power adapter is securely connected and the docking station is powered on.
- Verify the USB 3.0 cable is firmly connected to both the docking station and your computer.
- Check if the drive is properly seated in the bay.
- If it's a new drive, ensure it has been initialized and formatted (refer to Section 4).
- Try connecting the docking station to a different USB port on your computer or a different computer.
- Test the drive directly connected to a computer (if possible) to rule out drive failure.
- Slow Data Transfer Speed:
- Ensure you are connected to a USB 3.0 port on your computer. USB 2.0 ports will result in slower speeds.
- Verify that your operating system and drivers support USB 3.0 and UASP.
- The actual speed can be affected by the performance of your hard drive/SSD and your computer's system.
- Offline Clone Fails or Does Not Start:
- Ensure the target disk (Slot B) capacity is equal to or larger than the source disk (Slot A).
- Make sure both drives are properly inserted and detected by the docking station (power on, then off before cloning).
- Follow the cloning steps precisely, especially the timing for pressing the OTC/OTB button.
- Ensure no other USB devices are connected to the front USB ports during cloning.
- Card Reader or Front USB Ports Not Working:
- Ensure the docking station is powered on and connected to the computer.
- Try inserting the card or USB device firmly.
- Some systems may have limitations on simultaneous use of all front ports; try using one at a time.
