  1. Diskmgmt unable to shrink partition with free space


    On my main C:/ drive, there are 130 GBs of free space, which is visible in diskmgmt. However, when I try to shrink the partition, it says there are only around 8GBs of available shrink space in the new menu.I tried using other third party programs to shrink the partition but they also didnt work.Any ideas?

    :)

  2. undo partition shrink

    Hi,

    If you accidentally shrink the volume of your SSD partition, there is an option to extend the volume as well. To extend the volume of your SSD partition, follow the steps below:

    • Press Windows key + X on your keyboard and select Disk Management.
    • Right-click the partition that you want to expand and click Extend Volume.
    • Select the amount of space that you want to extend.

    Keep us in the loop with the result.

    Partition space

    You're not understanding this. Unallocated space is NOT equal as (partitioned) empty space.

    Unallocated space means empty RAW sectors on HDD. Empty space means an already allocated file system (either FAT32 or NTFS or any other) that is not occupied by any data.

    So in your case, as DanTheBanjoman already suggested, don't try to shrink "unallocated space", extend the main (C*Smile Diskmgmt unable to shrink partition with free space :) partition instead. You can't shrink something that doesn't exist (unallocated space), but you can extend the existing partition over unallocated space.
    So, just select the C: partition and extend it further. Program should automatically allow you to do that. I'm not using Partition Magic, but i usually done this with either:
    MiniTool Partition Wizard Free - manage and resize disk partitions (also for 64bit OS!)

    or

    EaseUS Partition Master - manage disk partitions (only for 32bit OS!)
