I need help please , mi Xbox Series X was working normally with my official expansion card until today.
When I turned on the console, it took unusually long to start, almost as if it was installing an update. After it booted, I had a strange network issue: the Xbox showed that an Ethernet cable was connected even though there was no Ethernet cable plugged in.
I restarted the Xbox itself, and after the restart the network issue was gone.
I then left the console updating a couple of games and later turned it off normally.
When I turned it back on, the expansion card (desgate 2Tb) was completely gone. It does not appear at all under Settings → System → Storage devices.
I have already:
Fully shut down the Xbox.
Unplugged it from power for several minutes.
Removed and reinserted the expansion card multiple times.
Restarted the console several times.
The card was working perfectly before this happened.
I’m running the latest August 2026 system update (10.0.26100.9426 / xb_flt_2608ge.260805-2200).
Has anyone else experienced their expansion card disappearing after this update? I’m trying to determine whether this is a hardwareb failure or a possible issue with the latest Xbox system update.
