2nd SSD Issues

In Files/On This Computer, I have Computer and SSD-512 (a 2nd SSD installed in my computer).I am having difficulties accessing this one.

I have gone on StackOverflow and fiddled around with some things, but have not fixed it. Right now, the SSD-512 is Mounted, but when I click on it, it brings me to a readonly part (containing $RECYLE.BIN and System Volume Information).

In /media/mike/ there is SSD-512 and SSD-5121. SSD-5121 is the readonly one and SSD-512 seems normal--I can touch testfile successfully there.

In short, what I want is to be able to move files to SSD-512, download to it, etc. in the Files GUI.
