I recently installed a WD_Black SN850X 4TB. I initialized the disk using disk management. Unfortunately, only half is "Healthy" can I can't do anything with the 2nd half. Extending is not an option (greyed out), can't initialize it either. I don't know what to do after searching a number of articles and YT videos.
