Windows 10: Storage Space drives not usable by new Windows 10 Pro installation

Struggling to find a solution beside formatting the drives and rebuilding the array. I've installed an SSD in my Plex server. The old Windows 10 setup included a Storage Spaces array. Thew new Win10 setup doesn't acknowledge the array or the drives. UEFI sees the drives, but they do not appear in either Disk Management or Storage Spaces.


Has anyone found a way to make the drives appear as an array without complete rebuilds?


Thanks

Calculate usable storage space with different size drives in Windows Storage Spaces?

While the above answer is correct for Raid-5, Windows Storage Spaces is a slightly different animal. For example, I have the following drives in a Parity Space formatted with ReFS (gotta use PowerShell in Windows 10 Pro if you want to use ReFS for Parity, as far as I can tell):

• 4x1 TB (3.63 TB usable)
  
• 3x2 TB (5.44 TB usable, 2.72 TB each)
  
• 2x3 TB (5.43 TB usable, 1.81 TB each)
  
• 1x1 TB (931 GB usable)
  

Total usable space before parity is 15.4GB (actual capacity of all drives). Total usable space after Parity is 10.2GB. Therefore, it appears in Storage Spaces, you can add up all usable space for the pool and divide by 1.5 to get an estimate for usable storage space on a Parity Pool.

Therefore, in your case you would have the following:

(2.72 * 2 + 4.54) / 1.5 = 6.65 TB of usable space.

 

How to remove a bad drive in Windows 10 storage spaces pool

Could someone list the steps involved in replacing a bad drive from a Windows 10 storage spaces pool? I cannot find any info on the Microsoft support site that is specific to Windows 10. Also, could you list the steps to remove a 'good' drive and replace
it with another drive if the process is different?

 

External Drive using storage spaces does not work on my new Win 10 PC?

Hi Leo,

Storage Spaces not only increase storage over time as you add drivers to your PC, it will also help you in protecting your data from drive failures. To isolate your concern, we'd like to know if you were getting any error messages when trying
to connect the external drive to your new PC. Also, can you tell us what troubleshooting steps have you tried so far?

In the meantime, we suggest that you run the Hardware and Devices troubleshooter to perform a diagnostic process on your system that will check and fix issues related to Storage Spaces. To do this, please follow the steps below:

• Type troubleshooting in the Search bar, then press
  Enter.
  
• Click View all from the left pane.
  
• Locate and click Hardware and Devices to run the troubleshooter then follow the next steps.
