Windows 10: Windows 11 File Explorer cannot read storage space drive

I am using Windows 11 Pro. I have a four disk parity array set up for local backup. The drive letter is E:. label Backup. Windows 11 and drivers are all up to date. The last time I restarted, Windows 11 File Explorer recognized the drive, and the drive letter, but just called it local disk. It says that it was unable to read it.

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

Storage Spaces Disappears After Replacing Boot Drive

Did you check Windows View update history list to see if KB4568831 has already been installed? I would think it has and that is why you got the message you did.

If you have not run the Storage Spaces troubleshooter there are instructions in the other link on do it manually. What is accomplished in either case is that your storage spaces will be set to read only which will allow you to have access to the data on your storage space drive.

The latter manual steps return the Storage Spaces drive to read/write and run optimization, defrag, and integrity routines. If your install is up to date then you should find the cumulative update KB4568831 installed in history. If you have upgraded to 20H2 then the patch discussed elsewhere to address the issue with Storage Spaces showing as RAW is rolled into the upgrade. In either case the manual optimization, defrag, and integrity routines can be run.
