I recently upgraded to a SSD. I used to run a 1tb HDD for windows and anything else. When I reinstalled windows onto the SSD I wiped the old HDD and then had it unplugged during the windows 10 install on the SSD. Ever since then the HDD does not show up in file explorer. I also tried a hard drive reader and that never sees it. However if I go into device manager and look at the drives section. I can see both the SSD and HDD, has anyone ever seen something like this before and knows how to fix it? For anyone questioning I plan to use the old HDD as extra storage as I have many games.
