Question Newbie mistake, led to disappearing of 2tb D: drive

[throwawayforqs]

Hello, after doing some Win10 optimizations on my new pc, I realized that my games were installed on my HDD instead of my SSD. So, instead of just manually uninstalling and reinstalling, I used some software called Macrium to automatically do it for me. And of course, it failed and my D: drive disappeared. I loaded the restore I set up earlier, and when I restarted, a new 550mb drive called System Reserved was in the place of my previous 2tb D: drive. I tried looking into Disk Management, and I wasn't able to find anything expect two unallocated portions of my 2 disks. I think that has to do with the solutions, but I'm not sure. Sorry if this is a really simple fix and I'm too new to realize, but could anyone help? Thanks.

You can't use Macrium to move games like that.
It is a full drive or partition cloning/imaging tool.


Disk 0 and Disk 1...which is the SSD?
I'm thinking Disk 1, the 500GB(465GB) ?

Yes, 500gb is my SSD and the missing 2tb is my HDD

So the OS was on the 500GB SSD.
What was on the 2TB HDD?

Steam games mostly and some downloads like MSI afterburner

Well, what you've done is overwritten the whole HDD.
You migrated the contents of the 500GB SSD to the 2TB HDD, and screwed up the partitions and whatever data was on the HDD.

We can migrate things back to the SSD if you wish, but whatever was on the HDD is gone.
(don't do anything until we establish a way forward)
