Microsoft says Windows 10 2004 breaks Storage Spaces on PCs/Laptop and servers


PCs, servers, and laptops with Windows 10 2004 may break Storage Spaces says Microsoft, no fix or workaround found yet

It seems that Microsoft engineers have bungled big time with the mega May 2020 2004 update since it was released on 6th June 2020.  First, it was the Windows 10 version 2004 Update error 0x80073712. That was followed by a benign issue of drawing on the Windows 10 2004 device connected to an external display that would make it go black. After two days we had a new Windows 10 2004 issue which did not allow users to make a fresh install. Microsoft calls it a new feature.  The latest was the No Printer issue caused by the KB4557957 update which did not allow Windows 10 2004 to recognize HP, Canon, and many other makes of printers. Microsoft released a fix for this issue today.

Now a fresh Microsoft bulletin says that installing Windows 10 2004 may break the Storage Spaces for some users. In the bulletin, Microsoft says users who have updated to the Windows 10 2004 version could experience issues using or accessing Storage Spaces configurations on some devices. This issue affects Windows Server, version 2004 users most.

For the uninitiated, Storage Spaces is a Windows and Windows Server technology that helps users protect their data from drive failures. It is conceptually similar to RAID, implemented in software. You can use Storage Spaces to group three or more drives together into a storage pool and then use capacity from that pool to create Storage Spaces. These typically store extra copies of your data so if one of your drives fails, you still have an intact copy of your data. If you run low on capacity, just add more drives to the storage pool.

The bulletin says that the issue is critical and Microsoft is investigating it. It has warned users who are affected by this particular bug not to run the CHKDSK tool in any case. At present, there is no workaround or fix for the issue. However, Windows 10 2004 users affected by this unique bug can access their data by marking them as read-only to continue using them. Here is how to do it:

Go to the start button and type PowerShell or press Windows key + X and select run Powershell as Administrator. If prompted by a User Access Control dialog for Windows Powershell, select yes. Once the Powershell starts, type in the following command and press enter.

et-virtualdisk | ? WriteCacheSize -gt 0 | get-disk | set-disk -IsReadOnly $true

Go back to Storage Spaces and you can see your files in read-only mode. Remember, you cannot edit them or write on them.

The other option is to deprecate your Windows 10 PC/laptop/server from Windows 10 2004 version to the earlier version. You can read about how to do it in this article.
