I fought this battle for a long time, tried every fix on the web I could find...IE turn off superfetch, 14 Tricks to Solve 100% Drive Usage in Windows 10, change this setting in the registry, etc, etc. Even bought a new hard drive..nothing worked. My machine
has 3 internal drives plus 2 external...mostly occurred on one drive, but the issue would float to others now and then.
I'm a coder and working with computers since DOS/1982, so have a reasonably good command...this issue haunted me. Drive would show 100% in Task Manager with 0 bits of data transfer, lock up the machine for 1 or 2 minutes, work right for a little while,
sometimes only 5 min, sometimes hours. I ran Check in the Tools under Properties, CHKDSK in CMD...nothing worked.
Here's what my issue was that NO post I read ever mentioned....BAD POWER SUPPLY. Makes no sense to me, but my power supply started shutting off in the middle of my work....then would work after a short rest (for a while), then turn off again. Put up with
that for a day than replaced it and low and behold...everyone of my drives are working like they should...I AM AMAZED! AND VERY HAPPY! Posting this in case it helps someone.
Thank you so much for this. I've been having the same issue for months and couldn't figure it out why. Every-time I'd unplug my adapter, The Disk usage would decrease dramatically.
