Microsoft publishes official manual workarounds for the Win10 version 2004 Parity Storage Spaces bug

Posted on July 2, 2020 at 12:15 CDT by woody • Comment in the Forums

A few weeks ago, I talked about the Win10 version 2004 upgrade deleting data on machines running the Parity version of Storage Spaces. If you’re running Parity Storage Spaces on a Win10 1903 or 1909 machine and upgrade to Win10 version 2004, your drive may show up as RAW (unformatted) in Disk Manager, and you can’t get to any of your data.

The just-released KB 4570719 says:
If you have already updated to Windows 10, version 2004 and are affected by this issue:

We recommend you check that the troubleshooter has run or apply the steps below and wait for a full mitigation or an update to address this issue. Attempts to mitigate the issue using methods not mentioned in this article might result in damaging of files, especially if the volume shows as RAW in Disk Manager.

Reverting to previous versions of Windows does not resolve this issue on affected devices.

We do not recommend running the chkdsk command on any device affected by this issue.
There is currently no full mitigation for all scenarios of this issue.

The “steps below” allow you to get at your data – with different procedures defined for WinFR and ReFS drives.

Tell me again who tests this stuff….
