they don't show up in my windows 10 custom made pc. now have two 1TB ssd that do not show up sort of. . they don't show in "This PC"/devices and drives....or in Disk management. They are seen in "device manager"/disk drives. they call them a just a "disk drive" and all I can do is update their drivers; not initialize nor format. That way, I gather, they would show up in disk management. and my drivers for them are all uptodate. I saw them in "storage spaces" too, but not as "named drives" and after I combined them in that program they still don't show up as a Drive you can move files' so I changed them to not show up in storage spaces.
