Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Enclosure not recognized by computer | Loose cable connection, insufficient power, drive not properly seated, incompatible drive, or driver issue. | Check all cable connections (USB and power). Ensure the hard drive is correctly installed inside the enclosure. Try a different USB port or computer. For new drives, ensure it is initialized and formatted in Disk Management (Windows) or Disk Utility (Mac). |
| Slow data transfer speeds | Connected to a USB 2.0 port, UASP not enabled/supported, or drive performance limitations. | Ensure the enclosure is connected to a USB 3.0 port on your computer. Verify your operating system and host controller support UASP. Check the health and speed specifications of your installed hard drive. |
| Drive not entering sleep mode | Continuous background activity, or system settings preventing sleep. | Ensure no applications are actively accessing the drive. Check your computer's power management settings to ensure they allow external drives to sleep. |
| Enclosure feels warm | Normal operation, especially during heavy use. | This is generally normal. The enclosure is designed with a sliding cover for better cooling. Ensure it has adequate ventilation. If it becomes excessively hot or causes errors, discontinue use and contact support. |
