Question: I have a brand new computer with an SSD and an HDD both plugged in with SATA. Windows is installed on the SSD (C:) and the HDD (E:) is practically empty.

I want the default windows libraries (i.e Downloads, Documents, Pictures etc.) to all be located on the HDD in order to save space on the SSD. I moved the downloads folder there using the properties menu (in the Location tab), but I guess I entered the Documents Folder location wrong and now it thinks the whole disk is that folder, and I can't restore it to default - I get an "invalid path" error.

Also, I tried right-clicking the Libraries folder and then restore to default with no help.

What it looks like:

Will formatting the HDD help? Any other advice?

Answer: 
Formatting should help, otherwise, try a system restore. Make sure you define an actual folder next time. Video: <https://www.youtube.com/watch?v=QG4LXw4Nd5U>
You might be able to use System Restore to roll the system back to solve this problem, if there is a restore point of course.
