I'm attempting to divide a newly formatted NTFS partition into two partitions. I could shrink the existing one and then format a new NTFS partition with the extra room. However, Shrink Volume is grayed out when I right-click on Drive D. Why and how do you resolve it?
According to your description, you only have one partition on your hard drive, where the Windows system and files are stored. Windows won't allow users to shrink or delete this partition to ensure the computer boot. However, third-party software and Diskpart can help you break the limitation and shrink the partition.
Way 1. Third-party Partition Shrinking Tool
EaseUS Partition Master owns multiple powerful features that can assist you in partition or disk management. If you find the shrink volume option is greyed out in Disk Management, try to use the "Resize/Move" advantage of EaseUS Partition Master.
Step 1. Launch this software before selecting the D drive by right-clicking and choosing "Resize/Move."
Step 2. Drag your mouse to change the shrink size of the target partition manually. Click "OK" to ensure the warning.
Step 3. Hit the "Execute xx Task" >"Apply" to execute the action.
Way 2. Diskpart
Diskpart can work for shrinking the system partition, but this way will consume more time and effort:
Step 1. Hold the "Windows+R" keys to enter the Run window and write cmd.
Step 2. Launch the command prompt, type the below commands, and press "Enter" after each:
diskpart
list volume
select volume P(Replace P with the volume number)
shrink desired=(Set the size you want to shrink)
exit
