Microsoft says that users could experience issues using or accessing Storage Spaces configurations on some devices after updating them to Windows 10, version 2004, or Windows Server, version 2004.
Storage Spaces is a Windows and Windows Server technology designed to protect customers’ data from drive failures by storing copies on multiple drives, much like RAID (redundant array of independent disks) but implemented in software.
“When using some configurations, partition for Storage Spaces might show as RAW in Disk Manager,” Microsoft explains in a support document published today.
Microsoft also added a note marked as “Important,” where it recommends users to avoid “running the chkdsk command on any device affected by this issue.”
No workaround available
While at the moment there is no workaround to prevent these issues from affecting some Storage Spaces configurations after applying the May 2020 Update, users can still access their data by marking them as read-only to continue using them.
To do this you have to follow the steps detailed in this procedure:
- Select Start and type: powershell
- Right-click or long-press on Windows PowerShell and select Run as administrator.
- If prompted by a User Access Control dialog for Windows Powershell, select yes.
- Within the PowerShell dialog, type the following command and press enter:
get-virtualdisk | ? WriteCacheSize -gt 0 | get-disk | set-disk -IsReadOnly $true
- Your Storage Spaces should now be set to read-only, meaning you will not be able to write to them. Your device will still be usable, and any volume not seen as RAW should be readable.
Microsoft says that these issues are currently under investigation and that an update will be provided when more information will be available.
