So last year I built a PC, and wanted to put my OS on my new SSD as often recommended. I did so and it made my SSD my primary drive, I wouldve like for my 1TB HDD to be the primary storage vs the 128GB SSD, but I can't find anyway to do this. Is the OS drive just always the primary drive? This means that sometimes applications can only be installed to the SSD and causes it to fill up SSD unintentionally. For future reference.
