Windows 10: Disk 0 (C: D:) at 100% (on multiple machines)

On my old laptop, my new laptop, and my desktop, Disk 0 will be at 100% almost always, and will spike up at random times. My desktop fan runs constantly, winding up and down when I haven't touched it for hours.

Any ideas what could be going on?? I've tried:
-Disabling background apps

-Disabling Windows Search

-Disabling Windows Defender

-Disabling McAfee

-Disabling Startups

-Disabling StorAHCI.sys driver

-Disabling Superfetch

-Full chkdsk reboot (It didn't fix this problem, but did take 6+ hours on both my laptop and desktop.)


Any other ideas? I can't imagine it'd be hardware related on all three machines, but who knows at this point.

Slow PC - 50% Disk Usage but 100% on C: Drive

Hi. i've seen multiple posts on the 100% disk issue and tried all of the previously suggested actions (disabling search, superfetch etc and all that). I had no 'slow' disk issues at all as MS updates seem to have rectified the situation in the Spring of
2018 for us. However, since a September Windows 10 update, we are slow to boot up and slow-running again. When I access the task manager, processes tab, I see disk usage at 50% rather than the previous 100% give-away...

But when I look at the Performance tab, Disk 0 C: (the main hard drive of my machine) is operating at 100% nearly all of the time...

Does anyone have any thoughts on how to fix this issue please a the general running speed and in particular the boot up speed has deteriorated significantly. And in advance, I'm grateful for all suggestions but please don't suggest buying an SSD as I'm
looking for a way of undoing whatever problems MS has caused again rather than having to pay several hundred Euros to fix faults they caused.

Cheers

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.

 

Cannot merge C drive (disk 0) with unallocated space (on disk 1)

Hi all,

I need some advice on whether it is possible - and if yes, how to merge my C drive on disk 0 with D drive on disk 1.

The problem is: my C drive is getting full soon, but previously after I deleted D drive and make it unallocated space (the bar of current D drive will change to black from blue), I still cannot expand C drive by adding the 100GB unallocated space into it.
If I right click on C drive, the "expand" item is in gray.

I've searched online for solutions but so far only have seen same questions around. Does any one know the solution and do a big favor to explain how to do it step by step? Thanks much in advance!

P.S, sorry that the interface is not in English. Below page shows the "Disk Management" function, and you can see that:

1) Disk 0 has 55.78G, including C drive (55.21GB), 100MB of something I don't know what it is, and 473MB of recovery zone

2) Disk 1 has 100GB D drive, and 831.51GB E drive
