I have bought this laptop since last year with a WD Green SATA SSD M.2 2280 as a extra, and the laptop itself was freedos so i had to install OS for it but i wondering if i was doing it right, cuz my HDD often doesn't recognized by the system and it was only SSD appear in File Explorer. It've still appear sometime and i could store a lot of game, document, .... in it, but somtimes it was like disable from the laptop, even in Disk management wouldn't display it either.

I have brought it to A warranties center of the store where i bought it. But after they gave it back to me it doesn't change anything my HDD still have the same problem. Can someone help me with it.
