Fix – Storage Spaces issue in Windows 10 version 2004
Microsoft is already aware of the issue and shared a temporary solution to deal with this bug. If you’re affected, then here’s what you need to do: Launch Elevated command prompt. For that, right-click on the start button and select Windows PowerShell(Admin). When UAC dialog appear, click Yes to continue. In the PowerShell window, you need to copy-paste this command: get-virtualdisk ? WriteCacheSize -gt 0 get-disk set-disk -IsReadOnly $true and hit enter. Doing this will set the Storage devices status to ‘Read-only’ resulting in any volume not seen as RAW should be readable. Are you affected by this bug? Does the workaround suggest above fixed the issue for you? Let us know in the comments.
