5. Setup Instructions
Follow these steps to connect your hard drive using the Poppstar adapter:
- Connect the SATA Drive:
Align the SATA connector of the adapter with the SATA data and power ports on your 2.5-inch or 3.5-inch SSD/HDD. Gently push the drive onto the adapter until it is firmly seated.

If you are using a 3.5-inch hard drive, connect the included 12V 2A power supply to the adapter's power input port. Then, plug the power supply into a wall outlet. 2.5-inch SSDs/HDDs typically draw sufficient power from the USB port and do not require the external power supply.

6. Operating Instructions
The Poppstar USB 3.1 Gen 2 Type C SATA Hard Drive Adapter is designed for ease of use with its plug-and-play functionality.
- Hot Swappable: The adapter supports hot-swapping, meaning you can connect and disconnect drives without needing to restart your computer, provided the drive is not actively in use.
