Cant load games on the series x

If you haven't already, I would highly recommend trying the troubleshooting steps below:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear

Then select System > Settings > devices and streaming > blue ray > persistent storage > clear three times > restart console.

Also, It would be great if you can delete the local save of the game.

If the issue still persists, try to soft reset your console!

It would just like to add that Series X|S games are developed to only use faster storage. Not only is this storage totally different to a mechanical hard drive, the way games are loaded is also different. In addition, the Xbox Series X|S hardware can leverage additional resources to load to games from internal SSD or external SSD's even faster, what Microsoft calls its Xbox 'Velocity Architecture'.

As previously stated, you're never going to be able load your Xbox Series X games from an external hard drive. They're just too slow.

Hi, yes that will be so, if you bought a game for the XBOX One, it will run better on the XBOX One X (FPS and loading times) and run even better on the XBOX Series X (FPS and loading times)

One thing I personally cannot say for certain is if those games loading from the external hard drive will run the same way they would if they were installed straight onto the console...

If you load games on the Series X or S from an external hard drive they will load the same as they do on a regular Xbox One. There won't be any performance issues. Games installed on a external SSD (SATA SSD not the Expansion Card) will load faster then
they would before due to the much faster I/O on the Series X/S.

If you move your games to either the internal storage or the optional Expansion card, you will see significant loading speed improvements. They'll be massive on a game such as Odyssey. Fast traveling in 5 seconds rather than 40 on a regular Xbox One or One
X!

To use the Series X/S 'Quick Resume' on Xbox One or other BC games will require said games to be installed internally or to the Expansion Card. Series X/S games can only be installed on the Internal or Expansion card.

No you cant play dics on a series s, only on a series x.
