Why Is Shrink a Partition Taking So Long? What Should I Do?

The disk I'm trying to partition has two 1TB partitions and is 2TB in size. My second one should be divided into a 600GB and a 400GB version. I instructed the drive to be shrunk by 600GB when I went to shrink it. This does not work. When hovering in the Disk Management, I only receive the loading cursor. I've been acting in this way for a while.

Why Does Partition Shrinking Take So Long?

Partition shrinking is a process that resizes the partition's space and makes it smaller. However, there are several types of data, like fragmentation, restoration points, hibernation files, and pagefiles, that cannot be deleted. Thus, when you use Disk Management to shrink the partitions that contain the above irremovable data, you will cost a lot of time. Furthermore, you may fail to shrink your partition due to this reason.
