Adding a drive to a pool gets stuck at 95%

[MikeG]

I have an enclosure with 4x8TB drives in it. I formatted them all to NTFS.

I added a drive to a pool and it got stuck at 95%. I had to abort.

There was a 2TB drive created in Disk Management that says that it's RAW. This drive won't mount in Windows Explorer. It lists an error if you try to access it.

I tried this all over again to see if the behavior was consistent. Everything happened exactly the same including another drive being created that I can see in Disk Management that is 2TB RAW.

At this point, I'm unable to add any drives to a pool, and I have two ghost drives (E: and F:) that are RAW that I can't format or delete.

Where to go from here?

EDIT: Ok, so I went ahead and reset Drivepool, and then tried to add a drive to a pool again. This time it "finished." But it still created a RAW partition that I can't access and no pool seems to have been created. But when I try to add that same disk to a pool again it says "can't add the same disk to a pool twice." 

Any idea what I could be doing wrong here?

Seems to be a known issue with Win10 insider builds of 2004.... There is another post - https://community.covecube.com/index.php?/topic/5374-win10-build-broke-drivepool-how-to-fix/

Looks like we are stuck until MSFT fixes whatever is breaking software raid! I am trialling DrivePool, because i had the same issue with Drive Bender, which stopped working when i updated my plex server... I had to roll back to an earlier release which worked fine (19635 - still the Manganese branch... now MSFT has moved to the Iron branch, things are broken again)

If you're on the Insider build, then there should be a fix, actually:
