Cura not seeing second HDD (where all my models are) in Ubuntu.

[mayhem8324 0]

Greetings all. 
I am using Cura under Ubuntu 21.10. I have all my 3d printing related files on a secondary storage HDD in my pc that is accessible to both my Windows partition and Ubuntu. 
Cura has been great to me thus far, but the hiccup of it not being able to open stl files from their true location is a pain. If i want to work with an stl, i have to copy it to the drive Ubuntu is installed on. Not to mention I loath unnecessary redundancies. Is there something Im doing wrong in Cura, or is this more a configuration issue with Ubuntu & Cura? I have the drive setup within Ubuntu to be automounted when I boot Ubuntu, so I know the drive is "there" and accessible. I don't believe I am missing something purely on the Ubuntu side that would be causing my woes, hence why I am starting here for help. But, I am not a Linux expert, per se (Not a novice, but know enough to be slightly dangerous, lol).
Any help here would be appreciated.
