Last month, Microsoft officially rolled out the Windows 10 May 2020 Update via Windows Update. Nevertheless, the update was seeded to a limited number of users as the company blocked it on a vast number of devices due to the numerous known issues. One of the issues that people complained about was Storage Spaces.
Today Microsoft published a support page (via Techdows) acknowledging the Storage Spaces issue. According to Microsoft, users might face issues trying to access Storage Spaces after updating to Windows 10 May 2020 Update. The bug affects some configurations of Storage Spaces and will show the partition as RAW in Disk Manager. Unfortunately, there is no fix or a workaround at the moment but Microsoft has recommended users to mark Storage Spaces as read-only to prevent from running into issues. You can follow the steps below to mark Storage Spaces as read-only on your system:
- Open Start Menu and type 'PowerShell' and open it as an Administrator (right-click and select 'Run as Administrator')
- Click 'Yes' if you get the User Access Control (UAC) prompt
- Type "get-virtualdisk | ? WriteCacheSize -gt 0 | get-disk | set-disk -IsReadOnly $true" in PowerShell (without quotes) and press enter
This will set Storage Spaces to read-only, meaning you will not be able to write to it. You can, however, still access it and "any volume not seen as RAW should be readable". Do note that Microsoft does not recommend running the 'chkdsk' command on any device that is affected by this issue.
Microsoft has published a separate known issues page as a reference for Windows 10 users who plan to upgrade to May 2020 Update. However, the company has still missed out on plenty of issues. Just a couple of days back we reported about the missing Fresh start feature that Microsoft moved without proper documentation. Microsoft is still working with different companies to squash various bugs like the problems with ThinkPad laptops and the Chrome bug that resets the credential manager.
