Not finding external hard drive after update...NEED HELP!

If the external hard drive is the possible cause then try and update something while the hard drive is disconnected.

It may be that your game is on the external hard drive but your default location for downloading games in your internal hard drive so when it goes to update it can't find the game as it isn't in the default location. If this is the case you would need to
make sure that the games being updated are on the internal hard drive before updating.

Does anyone know why my xbox one after the update won't find my external hard drive

The internal hard drive on the new Xbox series x is totally blank there is nothing on the internal hard drive zero zip so all my games are on the external hard drive told the machine to update to the external hard drive it will not update to the external hard drive do I have a defective machine I just bought it does it need to be returned can you help or not and if you can how to!?

Could be the external hard drive causing the issue then it won't be the first time I seen errors appearing after updates on external hard drives. Try installing it on internal drive instead if you can?.

You simply need to plug the external hard drive with the Xbox One games on it into the new console, then you can play games from the external hard drive, or transfer them from the external hard drive to the internal hard drive. You may need to update some
or all of the games, which will require the internet. But you don't need to re-download the whole game.
