[Errors] Having trouble mounting my external HDD.

[CychoSpawn]

Hello guys!

I am a bit new to linux, but I know a tiny bit. I used it here and there a few times. Before, I used Linux Mint and Ubuntu before. Now, I want to ditch Windows possibly for good. I tried plugging in my external HDD into my machine. At first, it mounted correctly and I could browse the files I have on there, but now I am having issues. I cannot seem to be able to mount it through the GUI nor the terminal. Here are the errors I get:

GUI:

Terminal:

How could I fix this?
Thank you!

Looks like something messed up the file system. What file system is on the drive?

With the drive not attached, open Konsole, type "sudo dmesg" then plug in the drive and run "sudo dmesg" again. See what new lines appear in the dmesg output.
