5. Operating Instructions
5.1. Read Mode (Connecting to PC)
To use the device as an external SSD enclosure for data transfer with a computer:
- Ensure SSD(s) are properly inserted and the dock is powered on (as per Setup Guide).
- Connect the dock to your computer using either the 20Gbps USB-C cable (for USB-C ports) or the 10Gbps USB-A cable (for USB-A ports). For optimal speed, use the 20Gbps USB-C cable with a compatible USB 3.2 Gen 2x2 port on your computer.
- Your computer should detect the SSD(s) automatically. The SSD LED indicator on the dock will light up when successfully connected.
- You can now access the SSD(s) like any other external drive. For new SSDs, you may need to initialize and format them through Disk Management (Windows) or Disk Utility (macOS) before use.

5.2. Offline Clone Mode
The offline clone function allows you to duplicate an NVMe SSD without connecting the dock to a computer. This process will erase all data on the target drive.

Figure 5.3: Setup for Offline Cloning.
- Prepare Drives: Insert the Source NVMe SSD into the 'Source' bay and the Target NVMe SSD into the 'Target' bay.
- Important Compatibility Note: Both Source and Target drives must be NVMe protocol SSDs. SATA SSDs are not supported for cloning.
- Target Drive Capacity: The capacity of the Target drive must be equal to or larger than the Source drive.
- Disconnect Data Cable: Ensure the USB data cable (to PC) is unplugged from the dock. The dock must only be connected to the power adapter for offline cloning.
- Power On: Turn on the dock using the ON/OFF switch.
- Initiate Clone: Wait for the SSD LEDs to light up (indicating drives are recognized). Then, press and hold the 'Clone' button for 3-5 seconds until the progress LEDs (25%, 50%, 75%, 100%) begin to flash.
- Cloning Process: The progress LEDs will sequentially illuminate and flash, indicating the cloning progress. Do not disconnect power or drives during this process.
- Completion: All four progress LEDs (25%, 50%, 75%, 100%) will remain solid when the cloning process is complete.
- Power Off & Remove: Turn off the dock, then safely remove the SSDs.
WARNING: Cloning will permanently erase all data on the Target SSD. Please back up any important data on the Target drive before proceeding.

7. Troubleshooting
- SSD Not Recognized by PC:
- Ensure the SSD is fully inserted into the bay.
- Verify the power adapter is connected and the dock is powered on.
- Try a different USB port on your computer.
- Ensure the correct USB cable (USB-C or USB-A) is used and is securely connected.
- For new SSDs, check Disk Management (Windows) or Disk Utility (macOS) to initialize and format the drive.
- Confirm the SSD is an NVMe type; SATA SSDs are not supported.
- Cloning Fails or Does Not Start:
- Ensure the USB data cable to the PC is unplugged. Offline cloning requires only power.
- Verify both Source and Target SSDs are NVMe protocol.
- Confirm the Target SSD's capacity is equal to or larger than the Source SSD's capacity.
- Press and hold the 'Clone' button for 3-5 seconds until the progress LEDs start flashing. A quick press will not initiate cloning.
- Ensure both SSDs are fully seated in their respective bays.
- Slow Transfer Speeds:
- Ensure you are using the 20Gbps USB-C cable and connecting to a USB 3.2 Gen 2x2 compatible port on your computer. Older USB ports (e.g., USB 3.0/3.1 Gen 1, USB 2.0) will result in lower speeds.
- Actual speeds can vary based on your SSD's performance and your computer's hardware.
- Device or SSDs Become Warm During Operation:
- It is normal for high-performance NVMe SSDs and the enclosure to generate heat during intensive operations like large data transfers or cloning. The open design helps dissipate this heat.
- Allow SSDs to cool down before handling them after heavy use.
8. Maintenance
- Keep the device in a clean, dry environment, away from direct sunlight and extreme temperatures.
- Avoid dropping or subjecting the device to strong impacts.
- Clean the exterior with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Ensure proper ventilation around the device during operation to aid heat dissipation.
