2. Setup and Installation
2.1. Device Layout

2.2. Hard Drive Installation
- For 2.5 or 3.5-inch SATA Hard Drives: Push the hard drive parallel into the 2.5/3.5 inch SATA Hard Drive Interface slot until it is securely connected.
- For M.2 NVMe & M.2 SATA SSDs: Insert the M.2 SSD vertically into the corresponding M.2 NVMe Slot or M.2 SATA Slot.
2.3. Initial Connection
- Connect the 12V 3A Power Adapter to the DC 12V Power Input port on the docking station.
- Connect the docking station to your computer using the provided USB-C to USB-C+A Data Cable.
- Press the Power Button. The blue Power Indicator light will illuminate. The corresponding Hard Drive Indicator light(s) will light up white.
Important Note:
- If both a 2.5/3.5 inch SATA drive and an M.2 SATA SSD are inserted simultaneously for read/write operations, the device will only recognize the 2.5/3.5 inch SATA drive. To read the M.2 SATA SSD, please remove the 2.5/3.5 inch SATA drive.
3. Operating Instructions
3.1. Data Read and Write
Once the hard drives are installed and the device is connected to your computer, they will appear as removable drives. You can then drag and drop files to transfer data.
3.2. Offline Cloning
The MAIWO K10835N supports bidirectional offline cloning without needing a computer. This allows for direct, bit-by-bit copies of your drives.

Important Cloning Notes:
- Always back up data from the target drive before cloning to avoid data loss.
- The capacity of the target hard drive must be equal to or larger than the source hard drive.
- M.2 SATA and 2.5/3.5 inch SATA hard drives cannot be cloned with each other.
- M.2 SATA and M.2 NVMe SSDs cannot be connected with 2.5/3.5 inch SATA hard drives when cloning with each other. Select the desired hard drive before connecting the device.
Cloning Steps:
- Choose the desired clone mode using the Clone Direction Switch (NVMe ⇆ SATA or SATA ⇆ NVMe).
- Insert the source hard drive into the 'Source' slot and the target hard drive into the 'Target' slot.
- Connect the power adapter. Ensure the cloner is NOT connected to a PC via the data cable during offline cloning.
- Press the Power Button. The blue Power Indicator and the hard drive indicators (SATA/NVMe) will light up.
- Long press the Clone Button for 3 seconds. All four progress lights will flash.
- Release the Clone Button, then immediately press it once again within 3 seconds. The 25% progress indicator will flash, signaling the start of cloning.
- Cloning is complete when all 25%-100% four indicators light up steadily. The hard drives can be removed after powering off the device.
3.3. Initializing New Hard Drives
New hard drives must be initialized, partitioned, and formatted before use. Please back up any important data on existing drives before initializing.
Steps to Initialize a Drive (Windows):
- Right-click 'Computer' (or 'This PC') and select 'Manage'.
- In 'Computer Management', navigate to 'Storage' > 'Disk Management'.
- Locate the new disk (often labeled as 'Disk 1' or similar, with 'Unallocated' space). Right-click on the disk and select 'Initialize Disk'.
- Choose the partition style:
- MBR (Master Boot Record): Select if the drive capacity is smaller than 2TB. Supports older Windows XP systems.
- GPT (GUID Partition Table): Select if the drive capacity is larger than 2TB. Recommended for modern systems.
- Right-click the 'Unallocated' space on the new disk and select 'New Simple Volume'. Follow the wizard to create a partition and format it (NTFS is recommended for Windows).
- Once the initialization and formatting are complete, your drive will be ready for use and accessible in 'This PC'.

5. Maintenance and Care
- Keep the device in a dry, dust-free environment.
- Avoid exposing the device to extreme temperatures or direct sunlight.
- Do not use harsh chemicals or abrasive cleaners. Wipe with a soft, dry cloth.
- Ensure proper ventilation to prevent overheating during prolonged use.
- Always power off the device and disconnect it from the power source before inserting or removing hard drives.
6. Troubleshooting
- Device not recognized by computer: Ensure all cables (power and data) are securely connected. Try a different USB port or cable. Verify the power adapter is functioning.
- Hard drive not recognized: Check if the hard drive is properly seated in its slot. For new drives, ensure it has been initialized, partitioned, and formatted (refer to Section 3.3). If multiple drives are inserted, remember the limitation: if both 2.5/3.5 SATA and M.2 SATA SSD are present, only the 2.5/3.5 SATA drive will be recognized for read/write.
- Cloning fails or does not start: Verify that the target drive's capacity is equal to or larger than the source drive's capacity. Ensure the cloner is NOT connected to a PC during offline cloning. Double-check the cloning steps, especially the button press sequence.
- Slow transfer speeds: Ensure you are using a USB 3.2 Gen2 compatible port on your computer for optimal speeds. The actual speed may vary based on the hard drive type (NVMe vs. SATA) and system configuration.
7. User Tips
- This device is highly versatile and useful for various data management operations, including backups, data migration, and system upgrades.
- For optimal performance and to avoid data loss, always ensure the target drive is properly prepared and has sufficient capacity before initiating any cloning process.
- When dealing with new SSDs or HDDs, remember to initialize and format them through Disk Management before attempting to use them for data storage.
8. Warranty and Support
