    Unknow Disk Usage


    Hi, I have a 128GB (120GB?) SSD as my C: drive and a 3TB HDD as my D: drive. I put virtually all my programs and data on the D: drive and have the SSD as a fast boot up with the essentials. Just lately, though, the SSD has been showing as nearly full: 106GB out of the max 117GB. However, when I check the usage by checking the properties of each of the main folders, the total only adds up to 71GB, leaving 35GB unaccounted for. The folder properties is set to displaying all hidden information. I have two accounts - mine and the admin, which is virtually unused and I accept this may take up a small amount of hidden info. I would try to delete unnecessary items or move any unimportant programs to the D: drive as most of them are, but the program file folders on the C: drive are relatively small, and the update folder is also small. I cannot figure out where the extra usage is. Any ideas? Matt

    :)

    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.

    Windows 10 100% disk usage problem

    Hi Jae,

    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.

    Thank you.
