Troubleshooting
- Enclosure not detected:
- Ensure the USB cable is securely connected to both the enclosure and your device.
- Try a different USB port on your device.
- Verify the M.2 SSD is correctly installed and seated firmly within the enclosure.
- If it's a new SSD, check your operating system's disk management utility to see if it needs initialization and formatting.
- Slow data transfer speeds:
- Ensure you are connected to a USB 3.1 Gen2 (10Gbps) compatible port on your device. Older USB ports (e.g., USB 2.0, USB 3.0) will result in lower speeds.
- Confirm your operating system supports UASP (Windows 8.1 or above, macOS, Linux).
- The performance of the SSD itself can affect transfer speeds.
- Enclosure gets hot:
- Some heat generation is normal during high-speed data transfer, especially with NVMe SSDs. The aluminum alloy shell is designed to dissipate this heat.
- Ensure the thermal pads are correctly installed on the SSD.
- Avoid placing the enclosure in enclosed spaces that restrict airflow.
