I have an asus gl752V it comes with a 1T HDD and 128gb SSD. I got the laptop last week and it comes without windows, only MSDOS installed on the SSD. So I have installed windows 10 on the SSD. Everything was perfect until I found out that the HDD isn't recognized. So I went to disk management and made "new simple volume" then format and then added a letter to the hard drive. Then it had shown up in "This PC". I wanted to change storage directory under System, but unfortunately the HDD doesn't appear in that screen. So I restarted the laptop thinking that changes apply after reboot, but then the HDD disappeared again from "This PC" and to make it show up again I had to do the above once again, but after I reboot it disapears again. Any idea what the problem might be?
