Unable to reformat a 1TB HDD but I can reformat other sizes.

Hey there! For the past month or so, I have not been able to upgrade any XBOX One S with a 1TB HDD. I keep getting the E100 error when applying the final update. It’s only the One S, and only the 1 TB HDD size.

I’ve been using the Andrew Paul method (popular on YouTube) for years with no troublel whatsoever, but with the October update of the OSU1, no 1 TB for me! 500Gb, ok, even a 640Gb is ok. It’s not the brand, tried Toshiba and Seagate drives.

Any ideas? Thanks in advance!
