We can't see what you've done from here. I can place a 500GB file on a 2TB partition, and I can analyze it later with "disktype some.file" and see what is inside the file. If what is inside the file resembles a hard drive, disktype will burst forth with a summary of the old disk drive layout. If there are file systems inside the file, a user can use a loopback mount, with a byte offset value, and that will allow reading or writing the partition *inside* the 500GB file. If the disk had been "dd" cloned to a second disk, then things like "gnome-disks" should see the file system sitting on the 2TB drive. Even disktype can see it (but should not be needed, as the OS does the analysis for us). sudo disktype /dev/sdb You have all the tools you need, at your disposal, to "determine what is inside a thing".
