How to delete a drive from the Storage Pool in Storage Spaces on Windows 10

Storage Spaces and Storage Pool

Storage Spaces help to protect data from problems with the drive and expand memory over time as you add the drive to your PC. You can use Storage Spaces to group two or more drives together in a storage pool and then use the space from that pool to create virtual drives called storage spaces.

These storage spaces usually store two copies of data, so if one of your drives fails, you still have an intact copy of the data. If you run out of space, just add more drives to the storage pool.

If you created a pool in Windows 10 or upgraded an existing group, you should be able to delete a drive from it. Data stored on that drive will be transferred to other drives in the pool and you will be free to use the drive for other purposes.

Note: You must be logged in as an administrator to remove the drive from a storage pool.

If you have trouble when you try to prepare a drive for deletion, it's probably because you do not have enough free space in the pool to store all data from the drive you want to delete.
