Another major Win10 version 2004 bug – Storage Spaces

Posted on June 17th, 2020 at 17:23

If you use Storage Spaces, best not install version 2004.

(I can’t repeat this frequently enough: Win10 version 2004 is
in the unpaid beta testing phase. Avoid it!)

Microsoft has fessed up to a small problem with Storage Spaces,
the feature that lets you pool drives to create a internally
backed-up blob of data. Storage Spaces doesn’t work on some
2004 machines, and if you go sniffing around the edges, you may
completely hose your data. According to KB

Devices using Storage Spaces might have issues using or
accessing their Storage Spaces after updating to Windows 10,
version 2004 (the May 2020 Update) and Windows Server,
version 2004.  When using some configurations, partition
for Storage Spaces might show
as RAW in Disk


We do not recommend running the chkdsk command on any
device affected by this issue.

There is currently no workaround for this issue. To
prevent issues with the data on your Storage Spaces, you
can use the following instructions to mark them as read

Sounds to me like another data-eating bug in a new version
of Win10. Can anybody out there confirm?

MS doesn’t bother to document the bug on the Official Release
Status Information page
