xBOX one refuses ssd drive

I followed the instructions for doing a 2TB upgrade on GBATEMP but im having issues with the SSD's

This works well on a standard 1TB drive. All works fine.
So I decided to get a 2TB SSD and do the same process and swap out the 1TB drive. Well it fails every time! it gets to "preparing console..." and then errors at 5% with either the 101 or 106 error code.

Next I did a direct clone of the Normal 1TB hard drive to the 2TB ssd and same result!

Next I tried a different make of SSD same failure. Tried different cables different caddies. All to no avail! Ive tried Kingtson Sandisk Crucial and WD ssd's Ive even tried cloning the SSD back to the normal harddrive which then works fine!

Im using OCU1 from Microsofts support page for the Xbox one and setting up all the partitions as per instructions. The Xbox OS version is 10.0.19041.4981

Tried using the USB method too for off line. Works for a normal harddrive but not any of the SSDs So what am i doing wrong?
