100% Disk Usage on my SSD while doing low-intensive work.

[Ardier]

Howdy!

For some reason, my SSD will show 100% usage in the Task Manager Performance tab will give readings of 0KB/s write and read speed, whilst doing simple things as watching videos online or browsing folders. It happened once while playing a game, but that hasn't occurred since. I have no idea what causes this problem. I've seen that it was a bug with Windows 10 and some SSD's, and ended a couple of services through services.msc, but to no avail. I've run malware checks and anti-virus programs to return no results, uninstalled programs that are no longer necessary, and can't figure out what my problem is.
I've disabled the MSISupported for the AHCI Controller, Windows search and Superfetch, turned off notifications and alerts, disabled Adobe Flash Player, and am about to do a ckhdsk.exe in command prompt, and return with the results once completed.

Any suggestions on what I can/should do to try and figure out this problem? Any help is greatly appreciated.

My specs are:

Windows 10 64-bit
AMD 8350 8 core 4.0GHz
16GB RAM
AMD R9 200 (Radeon HD 7950)
ASUS Sabertooth 990FX Motherboard R2.0
Be Quiet! 800W Power Supply
Seagate 2TB HDD
Samsung 650 EVO 120GB SSD

Thanks!

Windows has finished checking your disk.
Please wait while your computer restarts.

Here's the results from the chkdsk.exe. from what I can see there isn't a problem, just cleaned a few files.

I had the exact same problem and there are few ways to get it at least partially solved.
The problem is caused by some kind of Win10 power management bug (no one knows for sure).
Symptoms: random freezes for 30-60sec with PC being unresponsive.
Solution:
1) Go to Settings->System->Power&Sleep->Additional Power Settings
2) Instead of balanced, select "High Performance" plan

Alternatively you can modify your current power plan:
1) Go to Change Plan Settings -> Change advanced power settings
2) Scroll down to PCI Express and disable Link State Power Management

The second option is the one I use, and I was able to reduce my freezing from few times a day to about once every 2-3 weeks.

Additionally you can get rid of idle disk usage (when are not using your PC, but there is always some storage activity) by disabling Superfetch/Prefetch service.

Otherwise - write a letter to Microsoft with an official "Fuck You" and roll back to Windows 7.

Thanks, I'll give the first one a try, already have the Link State Power Management Disabled, whilst in the High Performace power plan, I just upgraded the power supply from 500W to the 800W as said above, so thought I could go to High Performance mode. Guess not... haha

The Prefetch service is different from the Superfetch, or are they bundled togther? I"ll go searching for it a disable that too.

I wish I could roll back, I did a couple of times before for other issues, which have been fixed before these problems occurred, and I don't think I can roll back any more. Stupid me for not creating a system restore for Win7 :\

In High Performance mode all power saving features are disabled, including PCI-E Link State, so it basically serves the same purpose, as the option #1.
Prefetch and Superfetch run separately, since they are two different services. Both may cause "hanging" state on HDDs and are pretty much useless if all of your apps are on SSD.

Disabling both:

Check with "Process explorer" and see what hogging the cpu/hdd

Ok cool, thanks. I'll disable prefetch now, couldnt find it in services so thought it was the same. Thanks for the guide!

My HDD won't have any processes going and usually sits from 0-5% whilst the SSD is at 100%. The CPU just chills out as well, and doesnt get close to max. I'll wait til it freezes next with Process Explorer open to see whats hogging either of these/SSD.

 

[Ardier]

So, here's a screenshot of Process Explorer and Task Manager when it just froze.

 

[manofthem]

I had this exact issue on Windows 7 and then shortly on 10; system drive would be 100% while additional hdds would be 0%. It would be the worst right after a restart too, then it would pop back here and there. The issue seemed to get better/go away after a clean install. Ultimately I don't recall what caused it or fixed it

 

[Countryside]

I had this issue with win 8.1
Disabling services and changing settings nothing helped but i found out the random hangs where caused by Asmedia sata driver.
Many times the 100% usage problem is caused by malware so make sure that your pc is clean.
Do a full scan with Malwarebytes and scan with Adwcleaner

Yea I've reinstalled Windows 10, to no avail :\

I'll look into the Asmedia SATA driver, cheers!
Have done a couple of full scans with Malwarebytes, will try out Adwcleaner and see if anything pops up.

random hangs where caused by Asmedia sata driver

ASUS Sabertooth 990FX only has a USB 3.0 hub IC from AsMedia (no SATA controller), but otherwise it is a valid point.
Asmedia controllers, especially ASM1061, are not only prone to driver problems, but also hardware failures.
My last batch of motherboards all had either 1074's or 1061's busted. In some cases they still work, but overheat like crazy (>90°C with RAM heatsink on top).
Still waiting for replacement ICs from China...

You will need to add the columns for hdd i/o read and write
View-columns - add process i/o - add read + write

Odd that the hdd is 100% active with no read or writing taking place
You cant see which service is using hdd in task manager? add Hdd to columns also

 

[nullington]

Try a windows SSD optimize run. Maybe there were some deletions done without TRIM.

So should I be worried about it with the motherboard I have? I installed it last weekend, so I hope that isn't an issue...

Just added those columns to each, will update with a reply when it freezes again.
I used Adwcleaner as stated above by Countryside, which found 9 files and removed them, and have yet to have any freezes, although I haven't let my computer be in a low active state in the last few hours, which is when the freezes occur.

Just keep an eye on your USB3.0 behavior. It does not happen often, or immediately, but we had quite a few of AsRock SoC boards with failed AsMedia USB3.0 and SATA controllers after 12-18mo of service.

I managed to get the Disk column for Task Manager when it froze, and its sorted from low to high...
Doesn't make sense to me...

I'll try and get the I/O read and write from Process Explorer on the next freeze.

Is there any where/any program I should use to monitor that?

Just got a screenshot with the I/O Read and writes, wasn't sure what to have it sorted by, so I hope I did it by the right one.

 

[silentbogo]

Nope. Just the symptoms, such as unusually slow/non-working USB ports, BSODs and high temperature on AsMedia controller.
But, as I said earlier, you shouldn't worry about it (it might've simply been some flaw in AsRock board design in my case(s)).

Ok, I haven't noticed anything odd with any of my USB devices, portable hard-drives and xbox controller haven't had any connection issues, nor with my mouse and keyboard. Not sure what it is...

Malwarebytes, Avast, adaware, spybot sd.

Maybe, this: Task Manager might show 100% disk utilization on Windows 10 devices with Message Signaled Interrupt (MSI) mode enabled

Already tried that, to no avail

Malwarebytes, Avast, adaware, spybot sd.

Will give those a shot and see what happens. Thanks
