Xbox External Drive Disconnection
Using a USB external hard drive with an Xbox Series X and it keeps disconnecting .
Symptoms
The drive was sat on a shelf, so not moving, and the cable was properly connected. It’s an Xbox branded drive, so compatibility shouldn’t be an issue.
Solution
In my case the hard drive was connected to a USB port on the front of the console. Plugging it into the a USB port on the rear of the console instead appears to have remedied this issue.
