Half of my SSD storage has vanished

[gabell]

I have an MSI laptop that had a 1TB SSD. Now half of my space has just seemingly disappeared somehow after I restarted my laptop while trying to fix a game. When I opened up my disk manager one of my hard drives / disks (whatever they are called) was gone leaving only one of them left. Heres a current screenshot of my disk manager, I think I had a disk 0 and a disk 1, now I only see disk 0 http://. Also since I have an MSI laptop I opened up my dragon center program to see what it said about my specs. Previously it showed that I had a 1TB SSD, now it says that I only have half of the space I did previously. Im mostly interested in recovering the space that I lost, I don't care too much about recovering what I had on it as I barley put anything in there yet. If anyone has any advice for me please respond, I haven't found any solutions to this issue yet.

That is showing a single physical drive, of 475.81GB
2 main partitions - Windows of 301.58GB and Data of 152.16GB

"475GB" is exactly what a typical advertised "512GB" drive would display as.

What, specifically, told you there was:
A: 2 physical drives in there
and
B: One of them was a 1TB


Can you open up the bottom of the laptop and eyeball the physical drive(s) in there?

Install and run Speccy. Post a screencap of what it says about the drive(s)

Heres a link to the screenshot of what the program said about my drives https://gyazo.com/06d51b2204b3624c4f8dd1cf0783f708

I know I originally had 1TB because thats what it said when the laptop was bought, and that is what I previously had. To be more specific about my disk manager I saw what was in the picture (disk 0) ,and before it got removed, I had another thing if I remember correctly was called disk 1 which was located on the empty space right below disk 0. disk 1 alone was not 1TB but rather it had the same amount of storage as disk 0 so with the two of them together I guess I had around 1 TB

So you had 2x 512GB physical drives.
It seems that one of them is gone.

Either dead, or possibly just disconnected.
