About as well as it can be, the laptop does not use screws to hold the HDD, this initially seemed to support my theory of a faulty HDD.
The laptop has like a black thin plastic cover over the 2.5" bay, with a small portion being sticky... and thats that.
TL DR Recently bought new SSD intended to host Steam Games, disappears when launching said games.
