Hello,
We could try to remove a physical disk from the Storage Pool under device management check if it works.
Press Win + X and choose Disk Management.
In the lower half of the Disk Management window, you can see a graphical representation of all your drives that includes storage space drives.
Right-click on the disk that you want to remove from the storage pool and select Remove Mirror.
A new window will open asking you to select the disk to remove. Select the disk and click Remove.
A warning will appear that the data will be lost. If you’re sure you want to remove the disk, click Yes.
The drive is now removed from the storage pool. You can see this in the lower half of the Disk Management window.
Now, you can format the disk and use it for other purposes. Right-click on the drive and select Format...
Choose your settings (usually the defaults are fine) and click OK.
Please make sure you have a backup of all your data before removing a disk from the storage pool as it will delete all the data on the disk.
Best Regards,
Hania Lian
