Problem resolved…well, almost I think.
I entered attrib g:\recycler -s -h and now I can account for the previously invisible 37 GB of data in Windows explorer. 
Does the DOS window override Windows Explorer because I set Windows Explorer to allow me to view all files - including hidden and system files - but this “recycler” folder was still invisible.
What the hell are these potentially giant sized “recycler” folders for anyway?
Thank you.
