How do I reformat my Secondary Hard Drive?

[Unpolarize]

Long story short, I had to wipe my SSD boot drive and reinstall Windows 10. Since then, I've been running into a few issues with my secondary hard drive containing programs and games not recognized by windows, so I can't uninstall them properly. I already decided on wiping my hard drive and start clean as if I had just purchased a new hard drive (also want to look for any bad sectors). However, when I try to format my hard drive, disk manager prompted me with a warning of how the drive is currently in use, and how formatting could cause unexpected problems with programs.

Here is the exact warning:

I also checked for page filing:

This has been driving me nuts. I'll greatly appreciate it if someone could help me.

This is a good first step in checking whether the drive is needed to boot windows; however, the problem at hand may be multifactorial. Try that step first. Second, check your page filing as I previously did. Third, try defragmenting your drive, whereas this ended up solving my problem altogether.
