My Xbox series x won't work when my Seagate external hard drive is plugged in, can you help...

First if it's an xbox series x optimized game moving it to an external drive won't work

Only bc titles that arent patched can

You can look at your library to see which ones are optimized or patched for the fps booster

Only the external nvme for series x Seagate cards work with optimized games

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.

Any games that are Series S/X optimized can only run on the internal hard drive or the Seagate Expansion card. The external hard drive you are using can only store them.

Hi,

External hard drives are not fast enough for Xbox Series X|S titles. Unfortunately you can't play these games off slow USB external hard drives. They need either be installed internally or to an optional Xbox Series X|S Expansion card.

Xbox Series X|S games can only be installed on the console's internal storage or the external Seagate SSD card. Link here. External drives are too slow for those games. The external hard drive can only be used to install backward compatible games (Xbox, Xbox 360, Xbox One).
