    I have just reformatted with 8 . I had exactly the same issue but in a differant way.

    The laptop was fine but when i opened taska manager i would see the disk usage climb from zero to 100% in a matter of seconds , the laptop would be sluggish and unresponsive. Closing task manager and all was well again.

    To see if it was task manger causing the issue i opened it waitied till it got to 100% then forced task manager to refresh by choosing the "always on top" in options. after hitting apply the disk usage would fall to zero then creep back up to 100%. As the issue only seemed to be there when in task manager and because i was strapped for time i didnt really look into it. But now 24 hours later the issue has gone??

    Just thought id share

    Unfortunately thats not the same for me. I cant recreate the problem, it comes on its own accord, but it doesnt seem to be related to task manager at all for me

    I just bought my Gateway labtop a few days ago. My disk usage stays in the 90's and sometimes at 100. I need help. Please and thanks.

    I had the same problem. Ive solved it deactivating Windows Defender:

    Win + Q
    Search "Windows Defender"
    Settings
    Administrator
    Uncheck "Turn on Windows Defender"

    Hope it works.

    I had the same problem, I run Windows 8 Pro from a 240gb SSD so I first tried cloning to a regular drive as well as updating the firmware on the SSD. However the problem still persisted. In the end the fix for me was to manually adjust the pagefile. When I checked my virtual memory pagefile was set to 1gb when I had 8gb of RAM installed. I'm not sure why it was set so low! So I set it to 16gb, rebooted and the 100% Disk activity subsided and the system is responsive again.

    This is happening to me on a brand new MSI CR70 I think my issue is related to the scheduled maintenance running but not actually doing anything. Disk activity is at 100% but nothing is really running and the laptop is very sluggish. I'm trying to fix a Windows Update problem which might be the cause

    Defragmentation/optimization scheduled automatically at noon once a week by default probably causes a lot of hangups for people. As far as I can tell, you don't have any notice that the defrag is happening after it starts (with only a tiny symbol appearing briefly over the "action center" flag to warn you when it does). You'll only see a large data transfer from the "system" process way down in the "windows processes" section below "background processes" of the task manager if this is causing it.
