- To power off, press the power button again. Ensure all data transfers are complete before powering off to prevent data loss.
5.2 Disk Management
- Accessing Drives: Once connected and powered on, the installed hard drives will appear as individual drives on your computer. You can access them like any other connected storage device.
- Ejecting a Single Disk: To safely remove a single hard drive, first ensure no data is being accessed from that specific drive. Then, use your operating system's safe eject feature for that drive. Once safely ejected, you can press the door button to remove the tray.
- Hot-Swapping: The enclosure supports hot-swapping for individual drives. After safely ejecting a drive via your operating system, you can remove and replace it without powering down the entire enclosure or other drives.
5.3 Daisy Chain Functionality
To expand your storage capacity, connect additional ORICO Daisy Chain enclosures using the USB-C HUB port on one enclosure to the Main USB-C port of the next. This allows for modular data management and significant storage expansion.

5.4 Direct Attached Storage (DAS) vs. Network Attached Storage (NAS)
It is important to note that the ORICO 9948C3 is a Direct Attached Storage (DAS) device, not a Network Attached Storage (NAS). This means it connects directly to a single computer via USB and does not have a built-in LAN port for network access. Data access is managed directly by the connected host computer.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Avoid using liquid cleaners or aerosols directly on the device.
- Ventilation: Ensure the cooling fan and ventilation holes are free from dust and obstructions to maintain optimal heat dissipation. Regularly check for dust buildup and clean as necessary.
- Environmental Conditions: Operate the enclosure in a well-ventilated area, away from direct sunlight, excessive heat, humidity, or corrosive substances.
- Safe Handling: Handle the enclosure and installed drives with care. Avoid dropping or subjecting the device to strong impacts.
7. Troubleshooting
If you encounter issues with your ORICO Daisy Chain 4 Bay Hard Drive Enclosure, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Enclosure not powering on. | Power cable not connected, power outlet issue, power button not pressed. | Ensure power cable is securely connected to both the enclosure and a working power outlet. Press the power button firmly. |
| Hard drives not detected by computer. | USB cable loose/faulty, drive not properly installed, drive not formatted, operating system issue. | Check USB cable connection. Re-install drives ensuring they are seated correctly. For new drives, ensure they are initialized and formatted in your operating system's Disk Management (Windows) or Disk Utility (Mac). Try a different USB port or cable. |
| Slow data transfer speeds. | Using a lower speed USB port (e.g., USB 2.0), cable issue, drive performance limitations, system load. | Ensure you are connected to a USB 3.2 Gen 2 (10Gbps) compatible port on your computer. Use the provided high-quality USB-C cable. Check the health and speed of your installed hard drives. Reduce other demanding tasks on your computer during transfers. |
| Drives unexpectedly disconnect. | Loose cable connection, power fluctuations, drive overheating. | Verify all cable connections are secure. Ensure the enclosure is in a well-ventilated area and the fan is operating. Avoid placing the enclosure near heat sources. |
