Windows 10: Create New Pool does not work on Storage Spaces

No matter what I try, the app "Storage Spaces" cannot create a new pool. I tried reconnecting and disconnecting my USB drives and nothing worked. Do you have any suggestions on how to RAID USB drives together as one? Thanks in advanced.

create storage pool

I had a USB storage device that became damaged and unserviceable attached to my laptop I had a storage pool with this storage device . I deleted the storage device and did the necessary steps that i know to unattached the device from the memory. I plugged
in a new storage device and tried to create a new storage pool. I keep getting the error r unable to create because it is being used by other apps.

 

create a new pool and storage space in the manage storage spaces

Dear all,

I have connected two USB storage drives, each one of them is 16 GB. I tried to create a new virtual pool but it did not work out.

I thought the size is not enough and it may need extra storage spaces. I connected 64 GB then opened the storage space but I am still unable to create storage space.

 

I cannot use any new Storage Spaces I create from my Storage Pool

Several years ago I purchased 2 refurbished Hitachi drives, installed them in my PC and used Windows Storage Space feature to configure them as a Storage Pool with 1 Simple Space and 1 Mirrored Space like so:


This set-up remained the same, even though I removed the drives from inside my PC and put them in a dual HDD enclosure, and also when I upgraded from Windows 8.1 to Windows 10. I am able to write to and read from these existing Storage Spaces, without problems.

Now, however, I want to make a third storage space from same pool, to experiment with BitLocker - mainly to see how badly it hurts performance:



After it finishes creating the new Storage Space, it gives me an error:



The new Storage Space appears in Storage Space UI (from Control Panel):



But not in File Explorer:



Which makes it completely useless, as far as I can tell.

Attempting to delete the new Storage Space repeats the same error given when the space was created, attempting to change the Storage Space gives a different error:



I am able to delete these useless spaces via Powershell method found in one of Brink's tutorials, but I would rather be able to make a functional new Storage Space. Anyone know how to fix this?

I just checked, and I think Disk Management shows the new Storage Space as Disk 8.

A bit more: right-clicking on Disk 8 in Disk Management's UI, brings up more options which led me to this tab:
