If you’re using a high-capacity SSD or NVMe M.2 drive, like a 1TB or 952GB model, it’s not ideal to keep your storage as a single large C: drive. Keeping all your data—documents, photos, music, and even desktop files—on the C: drive puts you at risk of losing everything if the operating system fails or if you need to reinstall Windows.

Creating a separate partition (like a D: drive) helps protect your personal data and makes future system recovery or reinstallations much safer and easier. In this article, we’ll show you two methods to partition your drive:
- Using Windows’ built-in Disk Management tool.
- Using EaseUS Partition Master, a powerful disk management tool with more features and a user-friendly interface.
Let’s get started.
📁 Why You Should Partition Your Drive
Partitioning helps by:
- Separating system files from personal files.
- Making data recovery easier in case of system failure.
- Allowing easier reinstallation of the OS without deleting your personal files.
- Organizing files for better data management.
🔧 Method 1: Partitioning Using Windows Built-in Tool
Step-by-Step Guide:
- Access Disk Management
- Right-click on This PC on your desktop. If it’s not visible, right-click on your desktop, go to Personalize > Themes > Desktop icon settings, and enable Computer.
- Click Manage, then select Disk Management.
- Select the Main Drive
- Find your primary disk (usually labeled Disk 0).
- You’ll see partitions such as:
- EFI System Partition (do not touch this).
- Recovery Partition (leave this alone).
- C: Drive – This is where you’ll create space for a new partition.
- Shrink the C: Drive
- Right-click the C: partition and select Shrink Volume.
- Enter the amount of space to shrink in MB (e.g., 83,000 MB = ~83GB).
- Click Shrink.
- Create the New Partition
- You’ll now see Unallocated Space.
- Right-click the unallocated space and select New Simple Volume.
- Assign a drive letter (like D:), choose NTFS as the file system, and label it (e.g., “Data”).
- Click Finish.
You now have a new partition ready to store your personal files safely.
