Question

Why Is My Disk Usage At 100%?

Oct 5, 2015 2:14PM PDT

So I haven't had this problem until getting Windows 10.

My startup used to be fast and I can go about doing my business in about 1 minute on startup. Now, everything is just absolutely bogged down. My Disk stays at about 100% for a good 10 minutes of my computer starting up.

I have disabled Windows Search and SuperFetch along with 'disable tips for Windows 10'.

Just a few suggestion I have ran into and nothing has worked.

I open my task manager during the 100% disk usage time and nothing is over .3mb, so I have no idea what is up with it.

Any ideas here?

AMD 6300 Six-Core Processor
8GB RAM
Windows 10
64 Bit OS

I agree. Tough to nail down what it is.

However I did luck out on one machine like this that we caught the HDD spinning down unexpectedly. That was my clue something was up with the HDD. The Seagate HDD (no I don't own it so I can't supply it for Seagate to test) passed the maker's testing but failed to clone. So it was a mess to move to the new drive.

New drive installed and after a hard long clone job (finally worked) the new drive is not showing the 100% disk usage.

Make what you will on this. Also, the 100% use was spotted on W7 and W8. Now that I've cured it more than once with a new HDD, I'm going to keep trying that. HDDs are cheap. Diagnostics and shop time isn't.

How to stop Disk Usage At 100% in Windows 10

I went around with this for hours with my VIAO, and did all the Net recommends; turned off SuperFetch, notifications, et al.. Finally I disabled the IAStorIcon.exe and like a miracle it is down to 0%-5% on idle with no programs running, after initial startup.

Just a hint, I had to change the settings in the registery because SuperFetch kept turning itself back on.

And for good measure run a full security scan and then make sure it is not running on 'full scan' mode all the time.
