Windows 10: 100% active time on disk D

Hi ive recently started having this issue with my pc and ive tried many ways to try and fix it but nothing worked so far. It has caused my relatively strong pc to slow down on restarts and downloading even tough i have a lot of space left. In the processes tab in task manager the disk usage is at a constant 50% but in the performance tab this is what i see. I need help.

100% Disk Activity Time and HDD health


Hi, having read a few reports found with a search on "100% disk activity, low cpu use" - from Win 8 onwards, I suggest:

a. disable readyboost if in use
b. disable defragmentation
c. try changing the power plan from balanced to high performance
d. if you use Intel(R) Rapid Storage Technology try updating it- see:
100% Disk Usage - Page 4
e. Windows Defender may be active whilst disk use is high.

These are things people have reported have had an effect. However, this doesn't necessarily identify an exact cause, so is unsatisfactory.

 

Disk Active time 100% Disk transfer rate 0

This is a problem I've seen reported countless times, on Microsoft support sites and elsewhere. Task Manager shows "Disk Active time 100% Disk transfer rate 0", and everything that's running on the computer freezes, although sometimes you can switch windows,
or even perform some operations within a window, but other times
everything freezes, including the mouse pointer. It usually lasts for 30 or 60 seconds, but sometimes it goes on for several minutes. Then it stops and everything goes back to normal, including Disk active time and Disk transfer rate.

It happens regardless of the apps I'm running or the activities I'm doing. I've even seen it happen with no user apps running at all - no browser, no file manager, nothing but background stuff. It happens every single day, regardless of whether there has
been a Windows update installed.

Microsoft gave me a fix for this problem a week ago, but it didn't work. Here are the steps I followed:

at admin command line prompt:

• Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• dism /online /cleanup-image /restorehealth
• reboot
• find driver file for Intel(R) 9 Series Chipset Family SATA AHCI Controller
  • C:\WINDOWS\system32\DRIVERS\iaStorA.sys
• Details tab from Properties window for controller
  • Device instance path:
    • PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA
• find registry key for disk controller
  • Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties
  • change MSISupported from 1 to 0
• reboot

The instructions I was given include this for Step 4: If you see “StorAHCI.sys” in the list, you are running the inbox driver. But my driver is iaStorA.sys, so maybe this
fix doesn't even apply to me.

After doing all of the above, twice, I still have the problem. I've seen this now over a period of about three years, on two completely different laptops, one a Toshiba running Windows 8.1 and currently on a Dell running Windows 10. I also have a Thinkpad
for work that runs W7, and I've never seen it happen on that machine. It got so bad on the Toshiba that I ended up discarding it, after spending countless hours trying to fix it.

I've also tried all the fixes I've found on the web, e.g. disable superfetch, disable BITS, add write permissions to Skype and the browser. Nothing I've found so far has helped. I also reverted Windows back to build 1703. That didn't help either.

 

SSD Disk Active time 100%

Yes, I run the test when the disk was completely idle and 0% usage.

AHCI is enabled. I also run the same test on my 2nd SSD and this one much faster:





I will clone my current system on that 2nd SSD and see if that help. I'm pretty sure that this was the problem.

I'll post back the results.

cheers
