Series x internal drive sometimes doesn't show installed games

Hi,

Your drive will work the same on Series X as it does on Xbox One and you won't need to format it.

However, Series X games or Xbox One games with Series X enhancements will not run from that drive and will either need to be installed internally or to an external SSD designed for Series X/S.

Your hard drive will be too slow for Series X games. They can be stored there, but not run from there.

Xbox Series X games can only be installed on the console's internal storage. External hard drives are not fast enough for those games.

You must install series X games to the internal hard drive. After which you can move them to the external for storage

You can use a hard drive that is USB 3.0 or 3.1 It doesn't have to be an SSD. I have a regular HDD myself and it works fine.

On the Series S/X, Series S/X games and upgraded One games will only run from the internal drive or the Seagate Expansion Card. You can still store the games on a USB storage device and move it to the internal to play if needed.

Not really...

Xbox Series X games / upgrades / updates has to be installed onto the Series X internal or expansion card SSD,

You can have Xbox One games on your external hard drive that will get an Series X upgrade but the games will need to be transferred to the Series X and then the Series X upgrade will need to be downloaded onto the Series X SSD,

As an example...

I have Marvel Avengers on my external hard drive that will get the Series X upgrade and I will transfer the game over to the Series X SSD ready to download and update the game to the Series X version when available.
