I recently upgraded to an SSD, but I also had my HDD with my old OS installed. I did a clean re-install but for some reason, my old HDD wont be recognised by Windows in My computer, but I see it in the BIOS. I can't reformat it using disk manager either. Any suggestions?
 
Solution
Right click on "Computer".
Manage
Under Storage, right click "Disk management".
Rescan disks

By the way, what kind of drive is it? SATA?
