ChkDsk Will Not Run! Immediately bails on "Volume is clean"

I typed into Command Prompt chkdsk /r, it told me that it cannot lock the drive, and asked if I wanted to run the utility on next reboot. I hit y to do so, I immediately restarted, and chkdsk took ONLY three seconds, it immediately bails out with "The Volume is clean." It did not run chkdsk at all! Even with a perfectly fine HDD, it should take WAY MORE than a few seconds to do a disk check. I tried to tell it to run again and the SAME thing happened on my Dell Optiplex 780. I Googled the problem but the ONLY results titled the problem were dodgy results, everything legit was unrelated results.

Anybody know what the problem is?

if necessary include the /f and /r in the command line as per Option2

You don't need /f and /r (note that option 2 does not say to use both).

If you enter chkdsk /? you will see that /r "implies" or includes the functionality of /f, with the additional analysis of physical disk errors. So you were correct, Sylveon with chkdsk /r.

Sadly, chkdsk failing to run typically indicates the bad has already failed or total failure is imminent. If you know the drive maker, you can download and run their diagnostics. See Hard Drive Diagnostics - listed by maker. Or you can run SeaTools which supports all drives.
