Windows 10 Pro, disk is visible in get-disk but not get-physicaldisk

Question

I have a Win 10 pro machine with one storage spaces pool. There are 6 disks: one with host OS, 4 disks are part of storage pool, last one is problematic.

Problem

I can not add the last disk to a storage pool. The disk also demonstrate strange behavior: it is visible by get-disk command and not visible by get-physicaldisk

Disk drivers are ok:

I can initialize disk, assign drive letter and write data on it.

`get-disk` and `get-physicaldisk` output

Add to storage pool

If I try to add disk to storage pool I get this error Can't prepare drives, Close all applications that are accessing the drive

What I have tried

there is a similar unsolved problem on SF and not much info on google: Disks showing up under Disk Management but not under Get-PhysicalDisk
I tried to initialize disk, format and clean it with diskpart

did you find a solution to your problem? I have basically the same problem.

Which Windows version are you using? I am on 20H2. I found a similar issue regarding storage spaces on 2004/20H1

For me it looks like this: get-disk vs get-physicaldisk

Nothing. I use Windows Pro N 10 1909 – ADOConnection Jan 02 '21 at 17:48
So, for myself I solved this by doing a backup, deleting the old storage pool and creating a new one. (I also noted that Windows 10 ENT can use ReFS on Storage Spaces) – Silece Jan 04 '21 at 12:45
