  1. System & Reserved files huge


    Hi All. I cloned my hard drive to a new Samsung 500 GB Hard drive. The problem I see is that the disk is nearly full due to the System & Reserved files being 318GB (see snapshots below). According to WinDirStat, only 145GB is being used. Looking at Storage, the System Files section shows 310GB, which is obviously way too large.


    Looking at diskpart, the drive is fully allocated with small recovery petitions.


    Any idea why my 500GB hard drive is acting like a 250GB hard drive or how to clean out the System Files that are hogging space?


    Thanks!

  2. System Reserved Memory issue

    Hi Rowan,

    The reduction in available system memory depends on the configuration of the following:

    • The devices that are installed in the computer and the memory that is reserved by those devices
    • The ability of the motherboard to handle memory
    • The system BIOS version and settings
    • The version of Windows 10 that is installed
    • Other system settings

    As an initial troubleshooting step, I suggest that you check your system for memory problems.

    Here's how:

    • Type mdsched.exe in the search bar and select the best match.
    • When prompted by the User Account Control, enter an admin user name and password, and click
      Yes.
    • Follow the on-screen instructions to run it.

    Let us know how it goes.

    Recovery Partition vs System Reserved Partition


    Thanks for all the info guys.

    Both original & target SSD's are listed as MBR as opposed to UEFI. I may have created a partition unknowingly in getting the original/new unformatted drive recognized, but I don't recall taking any steps that Windows did not step me through.

    Not that an upgrade to WIN 10 Pro is contemplated, but I suspect that having no System Reserved partition will not allow that to happen, after seeing how the original WIN 10 upgrade created a problem for some WIN 7 users that had a smaller 100mb vs 500mb System Reserved partition.

    System & Reserved almost full?

    Thank you for the information and posting back.

    High System & Reserved memory usage could be due to the following:

    • High Windows.old file(s) size
    • Large cache of trace files size
    • Windows 10 system file issues

    We would like to know some information to better isolate the issue:

    • Do you have a C:\windows.old folder on your C: drive?
    • Which Windows version and build are you using? Type winver on search box and press
      Enter.
    • What troubleshooting steps have you done so far?
    • Can you post a screenshot of what is inside the System & reserved storage? Double-click System & reserved. See picture below for reference.
