    Laptop constantly writing to disk


    Alienware 17 running Windows 10 Home. Works fine, but the thing is CONSTANTLY writing to the disk. I know this is way too imprecise to give me a definitive answer, but I fired up the resource monitor and the "system NT Kernel and System" process writes to dozens of files constantly...

    It's been on for over 4 hours and it's STILL writing constantly. Almost no reading...

    I have NOTHING running other than the stuff that starts with Windows, and VERY little of that since the Startup section of the task manager has pretty much every disabled. I even turned OFF wi-fi so it COULDN'T do anything stupid over the metered connection and it STILL sat there writing constantly

    I can't imagine that this is normal and I"m wondering how to figure out what to do next. Ideas?

    How To Format A Write Protected Flash Memory ?

    ¿You already tried this one?...

    Run CMD


    1. diskpart
    2. list disk

    Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

    2. select disk #
    3. clean
    4. create partition primary
    5. select partition 1
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

    good luck!

    Laptop constantly writing to disk


    Hi- RAID is in your system specs. Your last post is the first mention of a laptop....

    Unfortunately your attachment isn't valid for some reason.

    Please post your task manager screenshot or shots organising the relevant column high to low by clicking on the column tab like this when your PC should be nominally idle, using the icon to the left of the video icon above your post text, tooltip 'Insert Image'

    Being able to see what's running is a major starting point for suggestions.

    Then please try a clean boot, and again post a task manager screenshot or shots.

    I'll look forward to the Hard Disk Sentinel report (despite its name it does report on SSDs)

    There should be no need to turn Windows search indexing off on a properly functioning system - doing that is an XP or so legacy and should only be needed if diagnosing some particular problem.
