6. Maintenance
To ensure the longevity and optimal performance of your ORICO enclosure and the installed drive, consider the following maintenance tips:
- Handle with Care: Although the enclosure offers shock protection, avoid dropping or subjecting it to strong impacts.

7. Troubleshooting
If you encounter issues with your ORICO enclosure, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Drive not detected | Loose connection, faulty cable, uninitialized/unformatted drive, incompatible drive. | Ensure the drive is properly seated in the enclosure. Try a different USB port or cable. Check Disk Management (Windows) or Disk Utility (Mac) to initialize/format new drives. Verify drive compatibility (2.5-inch SATA HDD/SSD). |
| Slow transfer speeds | Connected to USB 2.0 port, UASP not enabled, drive performance limitations. | Connect to a USB 3.0 port (usually blue). Ensure your operating system and motherboard support UASP. Note that actual speeds depend on the drive's performance. |
| LED not lighting up | No power, faulty connection. | Ensure the USB cable is securely connected to both the enclosure and the computer. Try a different USB port. |
| Enclosure feels loose | 7mm drive without foam pad. | If using a 7mm thick drive, ensure the included foam pad is placed inside the enclosure to secure the drive. |
If the problem persists, please contact ORICO customer support.
