External HDD is getting Unmounted for no Obvious Reason
So, I have a HDD in a docking station that is connected via USB to my computer. I am running a python script stored on that drive that might be doing a lot of I/O (I didn't create the script, I am just using it). At the very least, the error messages tell me that it checks the current working directory a lot for some reason. The bottom line is that, when I run this script, the HDD unexpectedly gets unmounted at some point while the script is running. During my first attempt, it ran almost 48 hours before this happened. In subsequent attempts, it lasted 10 minutes and 40 minutes.
I checked both ends of the USB connection. While they have some wiggle room, it isn't enough to cause a physical disconnect (I tried). It also doesn't seem to be something with the HDD as simply turning off, then on, the docking station and/or unplugging and replugging in the USB cable seems to get the computer to remount the drive with no issues.
One thing I could try is running it using my internal drive. However, I am a bit nervous about what might happen if that ends up getting unmounted while the script (and all my other programs) is running.
Any ideas?

You could probably gain some information withzgrep '/dev/sd' /var/log/* | less
