Disk showing in Disk Management, But not DiskPart

Hello!

So, today I was doing a friend a favor, he had an old 1TB hard drive with important photos on it. He said he would appreciate it if I could move the photos to a different hard drive.

So, I hooked it up to my self-built PC (with a SATA port) and it didn't show up in file explorer.

So, I checked Disk Management to see if it would show up there, and it did. I later realized why it didn't show up in file explorer (Because it didn't have a drive letter). In Disk Management, I right clicked the primary partition only to find that it wouldn't
let me assign a drive letter.

I remembered there was another way to assign drive letters, with DiskPart. So I typed this into Command Prompt:

diskpart > list volume

In DiskPart, It showed the drive's EFI system partition (partition 1) but not the (Healthy) Primary Partition (partition 2).

Also in DiskPart, I could type "list disk" and it would show me the 1TB drive, if I then typed "list partition" it would show me the different partitions, but wouldn't let me assign a drive letter to them.

In summary, Disk Management showed the partition, but wouldn't assign a drive letter. DiskPart showed the partition 1, but not the primary partition.

My objective is to show the photos located on the 1TB drive's 2nd partition without erasing it.

I would be happy to add pictures if necessary.

Thanks!
