When it crashed windows flagged every drive for a scan at reboot but did not find any errors except one single file on the windows 11 drive that it fixed. It only took two seconds so I did not get a chance to get a good look at it and write it down.
The drives need to be thoroughly tested.
Please make sure that images or share links are posted for each step / test.
