3. Setup Guide

3.1 Installing Your Hard Drive/SSD

1. Gently slide open the enclosure cover.
2. Connect your 2.5-inch or 3.5-inch SATA I/II/III HDD or SSD to the SATA connector inside the enclosure. Ensure a firm connection.
3. Carefully slide the cover back until it clicks into place, securing the drive.

3.2 Connecting to Your Computer

1. Connect one end of the provided USB cable to the USB-C port on the enclosure.
2. Connect the other end of the USB cable to an available USB port on your computer (USB-C or USB-A, depending on your cable variant).
3. If using a 3.5-inch HDD, connect the power adapter to the enclosure and plug it into a power outlet. For 2.5-inch drives, external power is usually not required.
4. The enclosure is plug-and-play and should be automatically recognized by your operating system (Windows, macOS, Linux).

4. Operating Instructions

4.1 Data Transfer

Once connected, your installed HDD/SSD will appear as an external drive on your computer. You can drag and drop files, copy, paste, and manage data just like any other storage device. The enclosure supports 6Gbps transfer speeds with UASP acceleration, ensuring fast and efficient data movement.

4.2 Maximum Capacity and Power

The enclosure supports drives up to 20TB. For 3.5-inch drives, ensure the 12V/2A power adapter is connected to provide sufficient power for stable operation.

5. Maintenance and Protection

The UGREEN CM301 is designed with features to protect your data and ensure longevity:

• Heat Dissipation: The aluminum alloy casing and pre-set heat emission holes at the bottom provide excellent heat dissipation, preventing overheating during high-speed operations.
• Multi-Protection: Built-in safeguards include short circuit protection, voltage isolation protection, overheating protection, and ESD antistatic.
• Anti-Shock Design: The solid construction and softened rubber strip offer anti-shock protection for your hard drive.

6. Troubleshooting

• Drive Not Recognized:
  • Ensure the hard drive/SSD is correctly seated in the SATA connector.
  • Verify the USB cable is securely connected to both the enclosure and your computer.
  • For 3.5-inch HDDs, confirm the power adapter is connected and powered on.
  • Try connecting to a different USB port on your computer.
  • Check Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but uninitialized or unformatted.
• Slow Transfer Speeds:
  • Ensure your computer's USB port supports USB 3.0 (or higher) for optimal speeds. Connecting to a USB 2.0 port will result in slower transfers.
  • Verify that your operating system and drivers are up to date.
  • The performance of the installed drive itself can affect transfer speeds.
• Incorrect Cable Type:
  • If you received the wrong cable type (e.g., needed Type-A to Type-C but received Type-C to Type-C), you may need to purchase the correct cable separately. Ensure the new cable is compatible with USB 3.1 Gen 2 for full speed.
