Xbox series x - external hard drive patch 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.

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.

This article explains the difference between using a regular external hard drive versus the custom external storage for the Series S/X- https://news.xbox.com/en-us/2020/09...xbox-series-s-custom-storage-solution-primer/

An external hard drive used on the One will work for the Series S/X, but won't have the exact same performance as the one created for the Series S/X.

Yes you can plug in the hard drive on the Xbox Series X, and the Xbox One, Xbox 360, & Xbox games will be able to be played straight away. If you have games on disc, just insert the disc, and the game should play as it does on the Xbox One.

Just remember you cannot play Xbox Series X games from the external hard drive, only from the internal and external SSD storage devices that are available for the Series X.

No, just plug in the external hard drive, and your games that are stored on there will work straight away. There is no need to move them to the new console, only the Xbox Series X games have to be stored on the console or the external SSD storage that
is available for it too.
