Series X no longer reads 360 games

Like others I wasnt fully understanding but I think you mean about games released being exclusive to the series x or being available on the xbox one's. If so I read a few times it will be for at least 1 year after the series x release there will be no
exclusives but it could be longer

Hi,

Where did the Xbox 360 games come from? Another Xbox 360?

If they were downloaded via an Xbox One/Series console you can't play these games on an Xbox 360. Firstly the drive wouldn't be configured for an Xbox 360. Secondly, Xbox 360 games downloaded via an Xbox One or Series X|S are actually 360 games that have been converted to run on an Xbox One, they are no longer native Xbox 360 games.

Fair enough, a slow internet connection is as good excuse as any.

Be aware however that while that drive will work on Series X, you won't be able to play Series X games directly from it. Series X games will require faster access and read speeds. My understanding is that the Series X games can be 'backed up' on an external
drive and then need to copied/moved over to either the internal SSD or the External SSD's that will be available for the machine.

The Series X will read and play Xbox One games from an external drive though.

i think i remember being told or reading that all digital copies of your games are playable on series x and it will also be backwards compatibility to all previous xbox one, 360 and original xbox games

You should purchase a Series S, One X is no longer made and no longer supported for repairs even if you could find a new one. Series S will run all the new games for years to come.
