How Do I Fix My Seagate External Hard Drive From Shutting Down My Xbox Series S?

Hello again, exactly, from what we've seen so far the console is in perfect condition, to eliminate more possibilities should test your HD with another USB cable and also on another USB port of the console.

Quick question have you low level format the drive?

The only reason why a external hdd would forcibly reboot a system if you have bad sectors and it's needs to scan and reboot and repair said sectors

If you don't complete the repair it's just going to repeat itself

Hello again, what would be their Xbox One model, they usually have USB ports on the front and back.

Hello again, if you tested your external HD on another console and it also turned off, it means that there is some problem with your external HD, but it may be on the cable or even in the HD box.

Hello again, I understand that it does not have another cable, as already redefined the console and it keeps doing the same thing, will have to test it with another cable or even on another console, because as I mentioned this may be some electrical problem in the cable or even in the external box of the HD.
