When unallocated space is separated from your D drive by other partitions (e.g., E, F, or Recovery), Windows' built-in Disk Management can't help—it only works with adjacent space at right . A free tool like Partition Resizer solves this by safely moving partitions.
Partition Resizer Free (100% free tool on Win 11-XP) https://www.resize-c.com

Here’s the basic process:
Download and Launch: Get IM-Magic Partition Resizer Free .
Move Intervening Partitions: Right-click each partition sitting between the unallocated space and your D drive, select "Resize/Move," and drag the entire partition left or right to shift the unallocated space closer to D . Repeat for all partitions in the way.
Expand D Drive: Once the unallocated space is adjacent to D, right-click D, choose "Resize/Move," and drag its border into the unallocated space .
Apply Changes: Click the Apply button to execute all changes—your data stays intact .
Unlike Disk Management, this method doesn't require deleting any partitions, making it a safe and data-friendly solution
What can Partition Resizer do? Resize, move, delete, convert, format, clone, backup, migrate os and more.
