How to create a new d drive in windows 10 on my laptop

To create a new D drive in Windows 10, you can use PowerShe11 or Command Prompt with disk partitioning commands. Here's how you can create a new d drive in Windows 10:
Step 1: Open PowerShe11 as Administrator
    Press Win + X and select Windows PowerShe11 (Admin).

Step 2: Identify Your Disk
    Type the following command and press Enter: Get-Disk     
    Note the disk number you want to partition (usually Disk 0).

Step 3: Check for Unallocated Space
    To see existing partitions and unallocated space, type: Get-Partition -DiskNumber <disk_number>
    Replace <disk_number> with the disk number you identified.

Step 4: Create a New Partition
    If there is unallocated space, create a new partition:
    New-Partition -DiskNumber <disk_number> -UseMaximumSize -AssignDriveLetter    
    This will create a new partition using all unallocated space and assign a drive letter automatically.

Step 5: Assign Drive Letter D
    To specifically assign drive letter D

Step 6: Format the Partition

    Format-Volume -DriveLetter D -FileSystem NTFS -NewFileSystemLabel "NewDrive" -Confirm:$false
