    [Guide] How to remove a Physical Disk from Windows Storage Spaces WITH Parity

    Been bugging me for a while now that my USB drive was setup (incorrectly) as part of windows Storage Spaces and I've finally found a way to remove it. Thought it might be useful to some others on here, so here's the process:

    Step 1: Close any programs that might be trying to use the Storage Pool you are trying to remove the drive from. Yes you can have more than storage pool)
    Step 2: Open Windows PowerShell
    Step 3: Use the following command to identify the Friendly Name of the correct physical disk that you want to remove

    Step 4: Use the following command to identify the Storage Pool that you wish to remove the drive from.
    Step 5: Use the following command to "Retire" the Physical Disk from the storage This marks the drive as inactive and no further data will be written to it.
    Set-PhysicalDisk -FriendlyName 'PhysicalDiskXX' -Usage Retired
    Step 6: Rebuild the storage pool to compensate for the missing drive using the VirtualDisk storage pool that we got earlier, this is not quite the same as rebalancing, but its close enough for now that windows won't complain about there being a drive missing.
    Repair-VirtualDisk -FriendlyName 'VirtualDiskYY'
    This will likely take several hours so go play a game, sleep, go to work or whatever...

    Step 7: Remove the retired drive from the Storage Space manager so that windows will not try to include it in the storage pool when it comes back online.

    Remove-PhysicalDisk -FriendlyName 'PhysicalDiskXX'
    That's it! Simple.

    Full log below so you can see the results from each command as I ran it:
