Windows 10: Is it possible to shrink partition from HDD dock?

I have a 1TB HDD dock that I'm using to connect an HDD
This HDD already has Windows 10 installed on
I'm trying to shrink the main large NTFS partition to get a separate 300GB partition (I want to store some files there), but I get the following error:





Is there a way to shrink it?

Thanks

:)

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.

 

HDD Docking

Hi Tonyo,



Thank you for writing to Microsoft Community forum.

• What is the make and model of the computer?
  
• What is the make and model of the docking station?
  

The computer docking connections located on the bottom of the computer vary between computer models. For the docking station to work properly, the docking posts, eject mechanisms, and electrical connections on the docking station must be compatible
with the connections on your computer model.



Meanwhile, if the docking station is compatible, you may update the device drivers for your docking station and check if it works.



Update device drivers for docking station:

• Open the PC manufacturer support Web site, search for the
  Docking Station Driver for your PC model.
  
• Install the driver suggested and check.
  

If the issue persists, update the BIOS and try connecting the Docking Station again.



Note:

Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the
configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Hi, disk management has limitations on the size of shrinking partition. Also extending partition with Disk Management, you must have unallocated space next to the partition which you need to expand. Otherwise, the button is grayed out.

I suggest you use a third party free disk partition manager to help you to
extend the partition.
