My External hard drive will not allow me to download games on my Xbox Series S

I installed them on my old xbox one and transferred them to the external hard drive so I know they are on the hard drive

All my installed games appear correctly as installed on my Xbox one if I connect the hard drive to it. But when I connect the hard drive to my Series S, most of the installed games appear but about 9 of them do not. The missing games appear as ready to install on my Series S

Please tell users of the xbox one that once they allow the xbox one to format an external hard drive they will be unable to use this hard drive with there PC. I have very little interest in downloading the games i've played onto it. I mainly wanted to
download movies from my external hard drive to my xbox one for viewing movies. Same with songs (much like on the ps3 or even the xbox 360) I am very dissapointed with the download as it does not allow me to do this and futher more i now have a useless external
hard drive!

Hi,

Do you still have your Xbox One and does your external hard drive still work on that console?

I have successfully connected both my Seagate 'Game Drive' and my external SSD USB 3.0 drives to my Series S without any problems. All my installed games show up fine.

The Series X/S supports the same external drives as the Xbox One/S/X support. If your drive isn't being detected it's probably become corrupted or has a hardware issue.

Hi! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

I´m guessing you are having issues with optimized games right?

I´m asking you because to play Optimised for Xbox Series X|S titles, games must be installed on the console’s internal SSD (the default install location) or the Seagate Storage Expansion Card for Xbox Series X|S which is this one:

Hi,

Current external hard drives are USB 3.0 5,400 RPM mechanical hard drives. These drives are very slow compared to the Expansion card. You won't be able to run Series X/S games from current external hard drives, not even the 2.5" external SSD drives either.
But, you will be able to archive your Series X/S games to these drives to save downloading again.

The expansion card can run all compatible Xbox games. Which will be Series X/S, Xbox One and the BC Xbox 360 and original Xbox games on the BC list.

Xbox One and other Backwards compatible games will load a lot faster on either the internal storage or the expansion card than they would if you ran them off your external hard drive.

Microsoft has a video on YouTube showing 'The Outer Worlds' loading in just 11 seconds on a Series X/S SSD, compared to nearly 60 seconds on Xbox One.

I see. So how would i be able to transfer everything i have on my old hard drive to the new expansion card?
