PC Won't Allow me to Format a Hard Drive
I recently obtained a 1 TB hard drive for my gaming PC (not SSD). Steam cannot load games onto it and when I try and format it I get the error:
"Windows cannot format this drive. Quit any disk utilities or other programs that are using this drive, and make sure that no window is displaying the contents of the drive. Then try formatting again."
I have no programs running and no other windows open. How do I stop whatever program that is using my disk so I can format it? I did a brief search on the subreddit and internet and didn't find many matches to the specific text so I'm asking here.
PC is Windows 10 and the only things I've installed are Duckduckgo, Steam, Discord, and possibly Adobe Acrobat, all of which are closed.
Edit: I really appreciate how quickly people are offering advice but you're all assuming I know waaaaaaay more about computers and computers than I do.
