Operating Instructions
Game Storage and Playback
The Avolusion HDDGear Pro X is optimized for storing and playing Xbox One generation games directly. For Xbox Series X|S optimized games, they must be played from the console's internal SSD. However, you can store Xbox Series X|S games on the external drive and transfer them to the internal SSD when you wish to play them. Transferring games from the external drive is significantly faster than re-downloading them.

- Proper Placement: Place the hard drive on a stable, flat surface away from direct sunlight, heat sources, and areas with high humidity. Ensure adequate ventilation around the device.

- Verify the USB 3.0 cable is firmly connected to both the drive and the Xbox console. Try a different USB port on the console.
- Restart your Xbox console.
