100% Disk Usage, tried some methods found online.

Ok, bear in mind that assuming your disk is physically ok, as it seems to be, these are just basic preliminaries.

Once you've done a clean boot, monitor the task manager and again see if you can get the disk usage to spike at low transfer rates, and post a screenshot of the task man.

Then you can check your disk's performance with Crystal Diskmark. Here's mine:

Hi! I have done the clean boot. Heres my result before the clean boot, I've realised that the spike to 100% occurs when loading a webpage on chrome:

When Idle:


When Chrome is loading a webpage:



Doing a clean boot, task manager seems to be showing the same thing. However, Superfetch service host will occasionally cause the disk usage to spike to nearly 100% (Heres a bad picture of it as i couldnt get gyazo to work when internet is disabled, Sorry!):



I will download Crystal Diskmark and post my results later on.

Thanks!

Hi! Heres another update regarding Crystal Diskmark. After downloading and running it, here are my results:


As usual as Crystal Diskmark is running, disk usage shot up to 100%:



Thanks!

Ok that's the basics out of the way- nothing exceptional I think.
As you know, there are plenty of references to this kind of restricted disk throughput on the net.
Comparison: copying a file from my HD back to it..


History- do you have any idea as to when this symptom first became apparent?

Have a look at these (from previous thread)
On threads on this topic I read this suggestion:
" I resolved it by changing the power plan from 'Balanced' to 'High performance'. Instant results."

100% disc usage at 10 MB/s... what is causing this? I'm not going to have to do a full reinstall again am I?... : techsupport

7 Tips to Fix 100% Disk Usage Improve Windows Performance

Hi! I dont really have any idea when this problem first started. However, ive noticed a slow down in the computer for about a month or so and was deciding to clean up the computer only recently in which i found that the disk usage is unusually high.

I have tried the 6th tip from 7 Tips to Fix 100% Disk Usage Improve Windows Performance, still experiencing disk usage 100% with less than 10mb/s transfer rate when opening apps. However, I've realise that at times disk usage doesn't go all the way up to 100% when the transfer rate is 10mb/s or less. Any ideas? Is there any possibility that the disk drive might be failing?

Thanks!

Well, it could be related to the hardware interface.. rather than the disk surface..

Try 7 then 3 of that doct, making sure you can reverse the changes. Also experiment with a high performance plan.
Note- none of these should be regarded as real solutions in my view.

What might be interesting would be to connect a USB drive and see what happens copying a file from and to that (not using your internal disk).

How old is your laptop? Which OS did it come with?
Vaio S first came out in 2004..

On a completely different tack, try
a. Safe Mode - check the performance copying a file back to the internal disk as I did.
b. If still poor, download and boot from Kyhi's boot disk available from the top of the software and apps section here, and repeat that.

If you can demonstrate the hardware is capable of good performance, I'd suggest the problem may be a system driver incompatibility- old hardware, recent OS.

Hi! Well this laptop is 4 years old, and my computer has always been running on high performance with no changes in the power plans. It came up with windows 7 which might probably be one reason why some drivers may not be supported. I'll will try out some of the things u suggested and get back to you.

Forgot to mention that ive tried stopping superfetch, but the problem is still there. And Number 7 of that doct was the solution that allowed my laptop to not remain at 100% disk usage at idle.

Thanks!

Hi! I have tried booting into safe mode, any ideas how to view disk usage in task manager? as it is missing in safe mode.

Heres the image when a file is copied from external usb to internal hard drive (Not in safe mode):




Heres the image in safe mode: (Im not sure how do you check from disk usage in safe mode so here's just the resource monitor)


Well it feels that this has already occurred before creator update but im not sure.

Thanks for your help!

4 years sounds promising. But given Sony pulled out of the market, could be driver issues as I suggested- just a guess. The other two trial approaches should use some different drivers.

By any chance did you upgrade to the Creator's build about the time this started happening?

Do you recommend if I try to go back to the previous build of windows and see if this problem still occurs?
