Solved HDD spikes to 100% usage activity and video freezes

I was watching a .mkv video using media player. On several occasions the video paused on its own and didn't want to play.

When this happened, I notice my new HDD that I bought a couple weeks ago (WD Black 6TB WD6004FZBX) reached 100% usage, when it did resume the HDD usage dropped back to 0%

I close the player and retried to recreate the problem, but it couldn't make it happened at the same timestamp.

What's the chance that it's VlLC, or could it be my new HDD faulty?

Other than that, I don't think I notice any day to day issues. HDD passed all SMART tests and error checking on Windows.

Steps i tried:

plug and replug psu and sata cables
swap the sata cable with a difference one
Updated my VLlC player
tried a different movie

I can try playing the video on a different HDD/SSD to further rule it out.
