If you cannot create new partitions on unallocated space, it is most likely caused by MBR disks, which have a maximum hard disk capacity of 2 TB and support only four partitions or three primary partitions plus one extended partition.

To solve this give problem, you need first to convert the disk to GPT format. GPT has no limits on hard drive size and the number of partitions. Here are the details of how to convert MBR to GPT:

Step 1. Right-click "This PC/My Computer" to find "Manage" and click "Disk Management."

Step 2. Find the target partition, click "Delete Partition," and confirm it.

Step 3. Choose the MBR disk and select "Convert to GPT Disk."
