Microsoft has confirmed another major problem with Windows 10 version 2004 (May 2020 Update). This time the issue is significant and preventing some users from accessing Storage Spaces. It seems the problem is affecting users on Windows 10 and Windows Server.

If you’re unfamiliar with Storage Spaces, it helps Windows 10 protect data when drive errors occur. It is a part of the platform but is seemingly broken in Windows 10 version 2004. The feature saves two instances of data to ensure a copy is available if failures happen.

For some PC configurations, the partition for Storage Spaces is shown in Disk Manager as RAW. Microsoft says it is looking into the problem. Sadly there are no workarounds, so affected users should take steps to protect their data.

Marking items as read only can help you avoid losing data:

  1. Select Start and type: powershell
  2. Right click or long press on Windows PowerShell and select Run as administrator.
  3. If prompted by a User Access Control dialog for Windows Powershell, select yes.
  4. Within the PowerShell dialog, type the following command and press enter: get-virtualdisk | ? WriteCacheSize -gt 0 | get-disk | set-disk -IsReadOnly $true
  5. 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.

It is also worth noting Microsoft has inctruced affected users not to run the chkdsk command on their machine.
