Windows 10: Disk I/O FUBARed by update

Everything was more or less okay with my Win10 laptop for 1.5 years. Then suddenly after the .5GB cumulative update from April for my already installed 2004, these problems arose: -disk usage is almost always 100%. Transfer rate is usually low, as <50KB/s. 'System' (PID4) is at the top almost always, then whatever else is next varies from Registry to Sysmain to Diagnostic Policy to Defrag and so on. -the laptop often freezes up for 10 seconds to 10-30 minutes. Triggers might be scrolling a web page, starting or closing any program, right-clicking to get a context menu, etc. The freeze-ups appear to partly be because windows can't get at the pagefile quickly; e.g. ResMon shows Response Time of 10,000ms and so a delay occurred of 10 seconds for some trivial task. -it's looking as if the update somehow really really dislikes Firefox, as I can reproduce the problem consistently by opening many FF tabs - yet many many Edge tabs don't cause a problem. -even so, without FF running, sfc /scannow now running alone takes well over an hour to complete whereas it was 20 minutes previously. Task Manager might show rates of 18MB/s on the 1TB HDD. Then the Installer Worker goes idle for long periods; but usage is 100%. -without FF running, installing the latest .5GB security fix last week took eleven hours, using an already downloaded catalog msu. -the bad behaviour exists even on a clean profile -HOWEVER--- making Macrium R7 system images takes only the usual time. So I can sidestep most of the daily struggle by using Edge instead of FF. But the next WU is bound to take an eternity anyway, as does installing any program whatsoever. I've tried all the usual things. No virus, etc. I'm guessing a repair install might not help. Is a clean install the only avenue?

Windows 10 100% Disk Usage on startup.

Hi,

Thank you for responding.

I suggest you to try the below steps and check if it helps.

Step 1: First of all, take a note of the processes or applications that is running when the computer runs with high disk usage. Also, we need to find the applications that are running at startup.

Follow the steps to check for the processes under Task Manager:

• Press Ctrl+Shift+Esc to open Task Manager.
  
• Click on Processes tab. Check if any of the processes consumes high memory usage.

Bad sectors on the hard drive can be a cause for high disk usage.

Check which process is utilizing the Hard Disk on Windows 8.1, you may try the following steps.

• Open Task Manager and click on
  Details tab.
• Right click the columns headers and click "Select Columns".
• From the "Select Columns" window, check: I/O Reads, I/O Writes, I/O read bytes, I/O write bytes and then click
  OK.
• Now the columns will be added to the view and will display how much each process is utilizing from the hard disk.
• Sort by I/O read bytes or I/O write bytes by clicking on the column header to see which process is utilizing the Hard Drive most.

Step 2: If you have not run the 'check disk' scan or tried optimizing the drive, follow the steps from this article.

Improve performance by optimizing your drive

(Note: This applies to Windows 10 also.)

Important: While performing check disk on the hard drive, if any bad sectors are found on the hard drive, it tries to repair that sector and any data available on that might be lost.

Hope it helps. Feel free to get back to us for any further queries or issues related to Windows Operating System, we will be happy to help you.

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?
