What to do with a disk that won't pool
If you've got this error, you probably need to see a kitten right now
So I went and bought a pair of USB drives, went to 'manage storage spaces', and clicked on 'Create a new pool and storage space'. Easy! Except then when I actually tried to create the space it blew up.
Can't create the pool
Check the drive connections and then try again
PS C:\WINDOWS\system32> Get-PhysicalDisk | ft friendlyname,canpool,cannotpoolreason,size friendlyname canpool CannotPoolReason size ------------ ------- ---------------- ---- Crucial_CT750MX300SSD1 False Insufficient Capacity 750156374016(this is actually someone else's example - I forgot to grab a screenshot of my error before I fixed it!)
I went and googled about a zillion solutions, but this is the one that worked for me:
First, use diskpart to clean the disk. I hope it goes without saying this will destroy any
data on the disk. In fact, everything on here assumes you know that you will lose data on
any disk you do these operations on. So be careful. Anyway, diskpart:
I then used the Reset-PhysicalDisk -FriendlyName "[name of your disk]" command to reset the disk.
As you can see, once I did that the disk became able to pool.
Once the disks were correctly set, I was able to go back to Manage storage spaces and create the pool.
If you're curious, once I had the drive set up as a mirrored drive (I used the drive letter 'Q', I then turned on integrity streams in Powershell
PS C:\> Set-FileIntegrity Q:\ -Enable $True PS C:\WINDOWS\system32> Get-FileIntegrity Q: FileName Enabled Enforced -------- ------- -------- Q: True TrueThis is the Microsoft doc on integrity streams.
Please let me know if this has been helpful! If this has fixed your issue tell everyone about it! If it hasn't, let us know what else you've tried, and what worked for you!
