Operating Instructions
Connectivity and Data Transfer
The enclosure features a 2-in-1 USB 3.0 cable, compatible with both USB-A and USB-C ports, including Thunderbolt ports. This allows for flexible connection to various devices such as PCs, Macs, Linux systems, gaming consoles (Xbox, PlayStation), Smart TVs, and routers. Data transfer speeds can reach up to 5Gbps via USB 3.0, with UASP support enhancing performance up to 6Gbps.


LED Indicators
The enclosure features two LED indicators:
- Red LED: Indicates power status.
- Blue LED: Indicates hard drive activity (data transfer).
Auto-Sleep Function
The enclosure is equipped with an ASM1153e chip that enables an automatic sleep function. If there is no data activity for 10 minutes, the enclosure will enter sleep mode to conserve power and extend the lifespan of the hard drive. The hard drive will automatically wake up upon data access.

Maintenance
To ensure optimal performance and longevity of your ikuai hard drive enclosure, consider the following:
- Heat Dissipation: The aluminum shell and ABS inner tray are designed for effective heat dissipation. Ensure the enclosure is placed in a well-ventilated area.
- Placement: The enclosure can be used flat or vertically with the included stand. Choose a stable surface to prevent accidental drops.
- Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Avoid liquid cleaners or abrasive materials.
- Firmware Updates: Periodically check the ikuai support website for any available firmware updates that may improve performance or address known issues.

Troubleshooting
If you encounter issues with your ikuai hard drive enclosure, refer to the following common problems and solutions:
- Enclosure not recognized by computer:
- Ensure all cables (power and data) are securely connected.
- Try connecting the enclosure to a different USB port on your computer.
- Test with a different USB cable if available.
- Verify the hard drive is properly seated and secured within the enclosure.
- Check Disk Management (Windows) or Disk Utility (Mac) to see if the drive is detected but uninitialized or unformatted.
- Hard drive not spinning up or no activity LED:
- Confirm the power adapter is correctly connected and receiving power.
- Ensure the power button on the enclosure is pressed to the 'On' position.
- Test the hard drive in another enclosure or directly connect it to a computer (if possible) to rule out a drive failure.
- Slow data transfer speeds:
- Ensure you are connected to a USB 3.0 port on your computer. USB 2.0 ports will result in significantly slower speeds.
- Verify your operating system and drivers are up to date.
- Check if UASP is enabled on your system (if supported).
- Auto-sleep function not working as expected or disabling:
- The auto-sleep function activates after 10 minutes of inactivity. Ensure there are no background processes accessing the drive.
- If you wish to disable or modify the sleep function, check the ikuai support website for specific firmware tools or instructions, as this may require a firmware update.
