- Identify the correct slot for your drive type (M.2 NVMe/SATA, mSATA, or 2.5''/3.5'' SATA).
- For M.2 SSDs, gently insert the drive into the M.2 slot, ensuring the key aligns correctly. Secure it if necessary (some M.2 drives may require a screw, though the dock is designed for tool-free insertion).
- For mSATA SSDs, insert into the mSATA slot.
- For 2.5''/3.5'' SATA HDDs/SSDs, connect them to the SATA interface on the side of the cloner.
4.2. Power and Data Connection
- Connect the provided 12V 3A power adapter to the DC IN port on the cloner and plug it into a power outlet.
- If using the device as an external drive reader (Read/Write mode), connect the cloner to your computer using either the USB-C to Type-C or USB-A to Type-C data cable.
- Turn on the power switch located on the back of the device. The power light will illuminate.
5. Operating Instructions
5.1. Offline Cloning
The CR311 allows for direct disk-to-disk cloning without the need for a computer. This process duplicates all data from a source disk to a target disk.
Image: A visual representation of the offline cloning process, showing data flowing from a source drive to a target drive, emphasizing the capacity requirement where the target must be equal to or greater than the source.
Important Pre-Cloning Tips:
- Cloning is always from the Source disk to the Target disk.
- The Target disk's capacity must be equal to or greater than the Source disk's capacity.
- Cloning is limited to the same protocol: M.2 NVMe to M.2 NVMe, M.2 SATA to M.2 SATA, mSATA to mSATA, or SATA to SATA. NVMe and SATA protocols cannot be mixed for cloning.
- If the target drive has been used previously, it is recommended to wipe or format it before cloning to ensure a clean copy.
Steps for Offline Cloning:
- Ensure the cloner is powered off.
- Insert your Source disk into the designated Source slot (M.2 NVMe/SATA 1, mSATA 1, or SATA 1).
- Insert your Target disk into the designated Target slot (M.2 NVMe/SATA 2, mSATA 2, or SATA 2).
- Connect the power adapter and turn on the power switch. Do not connect the cloner to a computer.
- Press and hold the Clone button for approximately 5 seconds until the progress indicator lights begin to flash.
- The progress lights (25%, 50%, 75%, 100%) will illuminate sequentially, indicating the cloning progress.
- Once the 100% light is solid, the cloning process is complete. You can then safely power off the device and remove the drives.

Clone Time Reference:
The actual cloning time may vary depending on the hard drive's transfer speed and capacity.

5.2. Read/Write Mode (External Drive Reader)
The CR311 can also function as an external drive reader, allowing you to access and manage data on your M.2, mSATA, or SATA drives via your computer.

Steps for Read/Write Mode:
- Ensure the cloner is powered off.
- Insert your M.2 NVMe/SATA, mSATA, or 2.5''/3.5'' SATA drive into the appropriate slot. You can insert one or two drives.
- Connect the cloner to your computer using the provided USB-C to Type-C or USB-A to Type-C data cable.
- Connect the power adapter and turn on the power switch.
- Your computer should recognize the connected drive(s) as external storage. You can now access, read, and write data to the drive(s).

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Coolpie CR311.
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosols.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Avoid dropping or subjecting the device to strong impacts.
- Drive Slots: Keep the drive slots free of dust and debris. Use compressed air if necessary to clear any obstructions.
7. Troubleshooting
If you encounter issues with your Coolpie CR311, refer to the following common problems and solutions.
- Cloning does not start or fails:
- Ensure the target disk's capacity is equal to or greater than the source disk's capacity.
- Verify that both source and target disks are of the same protocol (e.g., NVMe to NVMe, SATA to SATA). Mixed protocol cloning is not supported.
- Confirm that the drives are securely inserted into their respective Source and Target slots.
- Ensure the power adapter is correctly connected and the device is powered on.
- If the target drive was previously used, it might contain partitions or data that interfere with cloning. Consider wiping the target drive using a computer before attempting to clone.
- Ensure the USB data cable is disconnected from the computer during offline cloning.
- Drive not recognized by computer in Read/Write mode:
- Check if the USB data cable is securely connected to both the cloner and the computer. Try a different USB port or cable.
- Ensure the cloner is powered on.
- Verify that the drive is properly inserted into the cloner's slot.
- For new drives, they may need to be initialized and formatted in Disk Management (Windows) or Disk Utility (macOS) before they appear in File Explorer/Finder.
- If using a used drive, ensure its file system is compatible with your operating system.
- Slow transfer speeds:
- Ensure you are using a USB 3.2 Gen 2x2 compatible port on your computer to achieve maximum speeds. Older USB ports (e.g., USB 2.0, USB 3.0) will result in lower speeds.
- The actual speed depends on the performance of the SSD/HDD being used.
If the issue persists after attempting these troubleshooting steps, please contact Coolpie customer support for further assistance.
