Disc 0 activity spike with freezing, can it be fixed?

[Otakumegane]

So for a long time now, no matter how much I changed the settings, there would be a random sudden short freeze that would last around .1 sec. Checking the task manager, I found that Disc 0 (No idea what this does) spiked to 100% usage every time during those freezes.

Why is this happening and can I fix it? I'm not sure if the game freeze is causing the spike or the spike is causing the game freeze.
