How to Make Storage Spaces Protective Partition Extend in Windows

What is Windows storage spaces protective partition?

Windows Storage Spaces Protective Partition is a system-created partition used by Windows to manage and protect the data stored in a Storage Spaces array. It is created automatically when you configure a Storage Spaces pool for redundancy (such as with mirroring or parity) to safeguard against data loss.

Typically, the protective partition is created on each physical drive that is part of a Storage Spaces pool. It's not meant for user data and generally isn’t visible or accessible to regular users. This partition shows up when you are using Storage Spaces to create a resilient, fault-tolerant storage pool.

The size of the protective partition is typically small (around 100 MB to 1 GB, depending on the configuration) and doesn’t hold any user data. It is hidden from standard file explorers, as it is essential only for the system’s operation.

In case of a failure, this partition plays a role in ensuring that the Storage Spaces array can be rebuilt or repaired. It holds recovery information that can help restore the system to its optimal state.

☞ Easy-to-use interface: The tool is designed with simplicity in mind, making it accessible for both beginners and advanced users. The step-by-step instructions guide you through the entire process.
☞ Resize/move partitions: AOMEI allows you to resize partitions flexibly. You can increase the size of your Storage Spaces protective partition by simply dragging its edge to allocate more space from an adjacent unallocated area or another partition.
☞ Extend storage space: You can extend your Storage Spaces pool by adding more hard drives or extending the existing partitions. This is especially useful if you want to increase the storage capacity without losing data.
☞ Non-destructive operations: One of the standout features of AOMEI Partition Assistant is that it performs partition management operations without affecting your existing data. This is particularly important when working with critical partitions, such as a protective storage space.
☞ Support for dynamic disks: AOMEI Partition Assistant supports dynamic disks, which is essential when dealing with Storage Spaces in Windows. You can easily manage and extend dynamic volumes without disrupting their integrity.

Step 1. Install and launch AOMEI Partition Assistant. Right-click a partition (here is D: partition) you want to adjust space and select "1-Click Adjust Space".

Step 2. If you want to use the space on F: to expand D:, you can simply drag the dot near the partition F: head backward to shrink the partition F: and enlarge the partition D: at the same time. Then click "OK". 

Tips: You can simultaneously drag the dot near the partition C: tail forward to shrink the partition C: so the D: will also be enlarged with the space of C: at the same time. In this case, you can adjust all partition space (C:, D:, and F:) on the disk.

Step 3. You can preview the operation by viewing the "Pending Operations". To commit the "Pending Operations", please click "Apply" and "Proceed".

Step 4. The process will start and you can check the progress. It might take time to finish the operation.

Step 5. Wait for the operation to be finished. After it is completed successfully, you will find D: is enlarged and both D: and F: are adjusted.
