    100% Disk Usage


    So.

    I have two 4 TB drives set up in RAID 1. RAID set up and configured using windows. I use them for storage of photos and stuff. For a little while they seemed to work fine.
    Now, whenever I try to access them at all (even just opening folders) they immediately jump to 100% disk usage. And they tend to just stay there indefinitely. If I try and copy anything off the drives it takes a very long time to copy and tends to move in chunks. Like 5-20 minutes to copy a couple of hundred MB onto my internal SSD kind of very long time.
    This has been happening for months now and I cannot figure it out.

    I can't tell in Task Manager or Resource Monitor what is using all the drive capacity.
    Task Manager under the Performance tab shows the drive at 100% usage in the top graph, but the second graph (Disk transfer rate) is basically empty, with the occasional tall narrow spike. I've killed all of the Tasks and stuff that I am confident enough to kill.

    If I look at them in Resource Monitor it shows the drive queue length as a blue line running right across the top (with occasional random tall narrow green spikes). Resource Monitor doesn't show which drive the things in it's lists are accessing, so it's hard to narrow it down (as I have a few drives), but all the ones doing the most are just things like "System" or "SVChost".


    I have tried this:

    and this:
    https://www.kapilarya.com/how-to-disable-superfetch-in-windows-10
    and I do not appear to have Intel Rapid Storage.
    I've run a virus scan. Nothing.
    I have regular Error Check and DeFrags set to go automatically on my non SSD drives, don't seem to have any issues there.

    I am on an up to date Windows 10.

    So yeah. This is super frustrating 100% Disk Usage :(

    :)

  2. 100% disk usage

    The most common cause of 100% disk usage appears to be Superfetch and Prefetch, but there are also other causes. You can try disabling both these features and see if it helps.

    This article provides steps to disable prefecth and superfetch:

    100% disk usage and memory usage

    Hi,

    100% disk usage and memory usage can be caused by a software corruption, running application running on the background and malware or virus infection.

    For us to properly isolate the issue and provide an appropriate resolution, kindly answer the questions below:

    • Did the issue happen after installing the Fall Creators?
    • Did you receive any error messages?
    • Can you send us the screenshot of the Task Manager showing the 100% disk usage and memory usage?
    • What troubleshooting steps have you done so far?

    For isolation purposes, please perform a clean boot to see if the same issue will occur. Refer to this
    article for more information on how to perform a clean boot
    in Windows.

    Looking forward to your response.
