Windows 10: Windows 11 won't read two new Seagate 4tb external HDD's at the same time

I don't know if that means anything. I've tried all the below but none works. - changing drive letters- formatting both HDD's- Uninstalling and reinstallingif I plug in one of the seagate ones in together with ano

Windows Backup can't find my seagate 4TB drive

Current build is Windows 10 Home version 1703. Seagate 4tb is formatted in ntfs multiple times now. I'm not getting error messages. Windows does find my other external disk Western Digital hdd 500gb in the back-up center but not the 4tb Seagate.

When I use right mouse button and then click automatic play on the Seagate 4 tb there is no "configure station for back-up" button but for the Western Digital 500gb it does appear in automatic play...
