Popking111555 · Dec 9, 2018

Hi there Microsoft,

I'm trying to shrink some GB from my hard disk C: to add it to D: because D: is on low free space and when I try to shrink C: it doesn't let me shrink as much as the free space that C: has, what I mean is that C: has like 150+ GB and it lets me to shrink like nearly 34GB something like that but I need to shrink more then that but it doesn't let me, why? is there something wrong with my system? or what? I really need to expand the D: storage size, please help me with this.

waiting for a reply...

Unable to shrink C: drive less that 480GB in Disk management on Windows 10.

Hello Lex,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Before assisting further, I would like to ask you few questions:

a. What happens when you try shrinking
C: drive below 500 GB, do you get any error message/error code?

To create a partition or volume (the two terms are often used interchangeably) on a hard disk, you must be logged in as an administrator, and there must be either unallocated disk space or free space within an extended partition on the hard disk.

The disk space of minimum 4GB and maximum of 8GB should be dedicated to Windows 10 installation files & folders on the drive in which the operating system is installed.

I suggest you to check the possibility of shrinking the drive by 420GB in the Disk management by following the steps below:

Press Windows logo + X keys on the keyboard and select
Disk management from the context menu.

Right click on the C: drive from the window and select
Shrink Volume from the context menu.

Enter 504000 in the Enter the amount of space to shrink in MB box and click on
Shrink.

Right click on the Unallocated drive which was recently created and select
New simple volume.

Follow the on-screen instructions and assign the drive letter from the window.

After the drive letter is assigned and the procedure is complete, right click on the newly created drive and select
Open from the context menu.

Check if the partition is displayed in the File Explorer.

Write to us with the answer to the above questions and the status of the issue on the same
post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

Thank you.
