My original hard disk drive partition is missing, and I don't know how to access it o

[BetaTime]

I stupidly and unknowingly tried to use the "Create a new pool and storage space" function on just my single hard drive. When I initially used my hard drive, I only had the single space, no partitions.

I then tried to use this "new pool" function that is under Settings > System > Storage > Manage Storage Spaces, thinking that it would do something else. Being that I only had one disk in the pool, it said "Failed to create a pool". Fine, I thought.

Then I noticed that my hard drive was not listed under This PC in the File Explorer, and I have no idea how to find it (I had originally called it ':Z'). I can't assign any saved files to that partition, either.

Under the Disk Management window, the 931 unused GB of the original 1 TB hard drive are listed under Disk 1 as "Unallocated". The Disk is online. But the original ':Z' space is nowhere to be found. That partition does not appear in the upper part of the window, where you would see the columns: "Volume, Layout, Type, File System", etc.

I have made a new ':Y' partition of 500 GB temporarily for use, though I still need access to the old files in the missing ':Z' volume.

Any help would be monumentally appreciated, though I understand that the issue is not too clear. I don't even really know what I did. The pool function returning an error should, in my mind, have left the original storage space unchanged.

Thank you.
