    Question about system disc


    Just finished downloading the new Macrium version, and am confused as what to do about my third partition (recovery partition ?) and why it is so large, and what I should do about it. I keep as much as I can on my H drive.


    Version 2004 OS Build 19041.572

    It's only a few hundred MB, less than one half of one gigabyte. How small were you expecting that partition to be?

    I believe that partition is his recovery partition. It will remain that size until a new version of windows is installed. It may or may not grow in size then. If the new version update needs more space, it will expand that partition. There is no need to do anything.

    Well it is 0.2% of the disk. I suppose you could delete it, expand C: drive and increase your free disk space by 0.2%. Personally, I would just leave it.

    Make a disk image of all partitions.
    If you want to gain some space, shrink the system partition to 100M but leave the recovery partition as it is.

    Thanks for the responses. I was getting ready to do a Macrium back up and when i saw that that partition was "colored red" I thought perhaps it would prevent me from installing the upcoming update. I did not realize until pointed out that Windows will dynamically control that size as needed.

    The red indicates low space available. Being such a small partition, space is pretty much low all the time anyway .

    hsehestedt Thanks it wasn't the partition size that worried me just that fact that Macrium colored it red causing me to think it might be a problem when the pending CU arrives.

    The red is just there to show it is nearly full. Oddly, if you click Macrium's 'Create an image of the partition(s) required to backup and restore Windows' on a UEFI system it will include the recovery partition, but doesn't if it's a Legacy MBR system.

    Strictly speaking the recovery partition isn't 'essential' but it does contain the WinRE that run when you boot to the Advance Startup options. Your windows will still boot normally even if you delete that partition, but you'd need a recovery drive or a Windows install USB if you ever needed Advanced Startup.

    I always include the recovery partition in my Macrium images.
