Windows 10 users are experiencing an error when attempting to create a new storage space using multiple drives, resulting in a 'Request is Not Supported' error. This issue affects individuals who have recently added new hard drives to their system, only to find that they cannot pool the resources of these drives together. The problem is particularly frustrating for those who rely on reliable data storage solutions.

The inability to create a new storage space with multiple drives can be caused by various factors, including drive configuration issues or compatibility problems with the Windows operating system.

⚠️ Common Causes

  • The primary cause of this error lies in the fact that the drives are not properly configured to work together as a storage pool. Specifically, the 'CanPool' status of each drive is set to False, indicating that they cannot be pooled for storage purposes.
  • Another possible reason for this issue could be related to the capacity of the drives. Although all the drives have been formatted and are empty, some may still have insufficient capacity to be added to a storage pool.

🛠️ Step-by-Step Verified Fixes

Configuring Drive Pooling

  1. Step 1: Open the Command Prompt as an administrator and run the command `bcdedit /pool delete` to remove any existing pool configurations.
  2. Step 2: Next, open the Disk Management console and identify the drives that will be used for the storage pool. Ensure that all drives are properly connected and recognized by the system.
  3. Step 3: Run the command `bcdedit /pool add ` to create a new pool configuration using one of the drives. Replace `` with the drive letter of the selected drive (e.g., 'C') and `` with a unique name for the pool (e.g., 'StoragePool').

Checking Drive Capacity

  1. Step 1: Open the Disk Management console and identify the drives that will be used for the storage pool. Ensure that all drives are properly connected and recognized by the system.
  2. Step 2: Run the command `fsutil disk get driveletter ` to verify that the drive letter assigned to each drive is correct. Replace `` with the drive letter of the selected drive (e.g., 'C').

💡 Conclusion

To resolve the issue, it's essential to properly configure the drives for storage pooling and ensure that they have sufficient capacity. By following the steps outlined in Method 1 or checking Drive Capacity using Method 2, users should be able to create a new storage space with their multiple drives.
