I bought a SanDisk SSD PLUS 240GB Solid State Drive. The issue i'm have is that for some reason its split into two hard drives a 147gb and a 75gb one. I want it to be together cause i want to download something but since its split neither can take it. I only have this SSD. I try to extend but i cant even do that.
