This guide will show you how to remove a drive from Storage Pool in Storage Spaces on Windows 10.
Storage Spaces and Storage Pool
Storage Spaces helps protect data from drive crashes and expands storage over time as you add a 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 the data, so if one of the 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 pool, you should be able to remove a drive from it. The 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 admin to remove the drive from a storage pool.
