Windows 10: Disk Active time 100%

Hi, since I swapped to Windows 10, I have been suffering from the HDD 100% Active Time, and as a consequence this makes the HDD speed crawl to an almost a halt 10 to 20 MB/s, sometimes less.I already tried all types of tests, and haven’t got to a conclusion.The only thing I haven’t done yet is attach the HDD to another PC, since I don’t have one near me and Tech assist Shops would require me to leave them the HDD for a couple of days or more that’s time I can’t afford right now.So, I’m looking for someone with real expertise that can advise me on how to get to a conclusion. I ll add 2

100% hard disk active time in windows11.

I already did these type of steps like formatting whole hard disk then clean install windows 11 and didn't install any third party apps only apps were windows stock

But still facing 100% active time hard disk but my hard disk usage was only 2% or 3%. My pc gets slow whenever active time reaches 100% and most of the time active time is always 100%.

 

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.

 

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.
