Hi all! I recently migrated all my files from my old WD Blue (1tB) hard drive to my new Samsung 970 evo SSD. I used samsungs migration software to do so and now my SSD is my boot drive and contains all my files. How do I proceed to clean up my hard drive? I am pretty sure I have all my files twice now, once on my old HDD and once on my new SSD. Is it ok to just format my HDD to use as mass storage? If so, how would I do this? Thanks!
