" Okay so, the same thing is happening to me, but i found out that when i open the dvd drive and close it, it stops blinking for a while. But then it starts doing it again! So i found a temponary workaround, just disable your dvd drive in the Device Manager and it will stop (at least it did for me and i have an acer laptop aswell).

Hope i helped "

yeah, i got the same problem

i dont know how to fix,

this  bug real suck,

im playing League of Legends, my fps going down like sh!t , under 10 fps, and keep freezing,

damn 100% disk

Unfortunately I tried CCleaner before without luck...

After many times, I realized that problem of high disc usage happens when I'm using Outlook 2013 (background or reading/writing mails). So, when It happens I do end the task of Outlook and few seconds after that, the disc usage became normal.

One more thing is interesting. Looking in Task Manager, others applications like Firefox, Trillian (internet in general) is showed as "not responding". But, just after end Outlook, all others are normalized.

I would like the share HAPPILY THAT I HAVE CHANCED UPON A POTENTIAL SOLUTION to this problem. That is optimizing the registry !. While installing a Bluetooth device driver I got a 183 error and while searching the solution suggested was to clean up registry. When I analysed the registry, I was amazed to notice that it was rather like a junk yard (3000 bad entries) than a vital storage necessary to run a complex OS & its apps. It means that many of the applications that we install and uninstall, including those from Microsoft (like Silverlight) leave some debris that affect the performance of the registry, it seems.

I used the CCleaner discussed in the link http://pcsupport.about.com/od/toolsofthetrade/tp/free-registry-cleaner-programs.htm. Take a back up of the registry using the Export menu in the 'RegEdit' program before running the cleaner. 

After this, the random spikes in disk usage is almost not there since the last 6 days. Others may please try this and share your experience.

1. The spike in the disk usage and consequent lock up of the PC for 4-5 minutes has been happening as randomly as just clicking on a tab of the IE or opening a small PDF  or even moving the mouse. Simply there was no pattern at all. I have tried disabling the Antimalware executable, disabling search indexing, increasing the virtual memory, upgrading to Win 8.1, removing all unwanted software, disconnecting network, etc. None of these have helped.
2. In two instances the disk usage definitely spikes even now. (a) If the auto update is on (I have kept it off now), (b) if the Windows has been idle for quite some time. In the later instance it appears that the MSMPENG.exe takes over and starts scanning the machine for virus / malware. To test this, start the Task manager (TM) window and switch of the monitor while the machine is on. Immediately you can seen that the red light glows indicating the spike in HDD use. When you switch the monitor on you can see the result in the TM.
3. Many times under the Processes in the TM, the System (ntoskrnl.exe) or one of the Service Host (Svhost.exe) processes show high Disk Usage while in Details tab one can see that the I/O read of the MSMPENG or IE or some other process goes up. It makes me think that the issue is inherent in the internals of the OS and it is time Microsoft looks deeper into this.
4. I am not quite sure why cleaning the registry would resolve this issue but that is breakthrough I have seen after struggling with this for over 10 months.

There are literally over a 100 threads in different forums, including 10+, in this forum about the high disk usage in Windows 7, 8 and 8.1 on PCs or laptops of different brands, configurations, types of HDD, etc. I suggest that Microsoft engineers take this serious and work towards a solution.

UPDATE:

After a several tests, a friend and I have narrowed this down to these 2 services and 1 executable:

1. Windows Update
2. WIndows Modules Installer (%WinDir%\servicing\TrustedInstaller.exe) and
3. TIWorker.exe (%WinDir%\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_6.2.9200.16613_none_6273bd8950d6cae2\TiWorker.exe)

Not saying (yet) that these are the ONLY cause, but whenever any of these are running, ntoskrnl.exe keeps the disk usage at 100%.

Any ideas?

Hello there,

after try a lot of tricks, I reach the same conclusion above. But, I have no idea how to solve the problem, just my impression is that it started after update to Windows 8.1 (from 8.0).

Now, I disabled the service "Windows Search", as the tip from other user here. Let's pray...
