Extracted a 2TB External HDD and transplanted it into my PC, it's showing as a 127MB drive.

Not true; i.e., "I'm literally the biggest idiot on the planet earth and a failure."

And not a waste of time either.

All too easy sometimes to simply get too wrapped up in it all. Proverbial "cannot see the forest because of the trees".

Mark it down as a lesson learned and just move on.

And enjoy all the new storage space and the fact that you did indeed salvage the drive.
Do you known the source of that "random external drive"?

Maybe a NAS drive? Make, model, enclosure....?

There may be some proprietary configuration with respect to the drive and partitions and folders within.

If you do not need any data from the 2TB drive then just reformat it as NTFS.


 


I don't need any of the data on it and I don't care about losing it. I tried reformatting but that didn't change anything.

The drive was in a Verbatim enclosure, and this is all the information that's on the label on the back;

"Model #USB2TB" "Lot # SH0Z15" (that 0 might be an O)
"Verbatim #96865"

That's literally it :/

I realize you've resolved this problem but I'm curious about your statement that Disk Management did not reflect the option "Change Drive Letter and Paths..." in this type of secondary drive situation since I've never come across that anomaly in my experience.

You did right-click on the partition in question, i.e., the 1862 GB partition on that 2 TB HDD, and you're indicating the sub-menu appeared with ONLY a single option - "Delete Volume"? That's precisely what occurred?
 


When I was told to right click on the 1.8tb partition I was unclear as to what he meant, so I was right clicking a bunch of other stuff which would result in what I saw. Just a case of user error. All I had to do was right click on the proper partition which I for some reason almost completely ignored and then prepare the drive normally.
