Storage Spaces

Microsoft has finally published an optional update to address at least four major bugs in Windows 10 version 2004, including Storage Spaces file corruption issue where the disk-failure protection feature is broken.

As we reported in June, users claimed that Windows 10 May 2020 Update could corrupt your files when you use the Storage Spaces ‘parity spaces’ feature, while others noted problems with disk defragmentation or Drive Optimize tool.

Windows 10 version 2004 bug corrupted partitions and damaged files in Storage Spaces’ party spaces and some users noted that their 20TB of data show up as ‘RAW’. Others reported multiple errors when attempting to open the Storage Spaces management from Settings or Control Panel.

While the problem with Drive Optimize tool remains unpatched and unacknowledged, Microsoft says it has included fixes for problems affecting Storage Spaces in Windows 10 Build 19041.423 (KB4568831) optional update. This patch also allows Windows built-in data protection software to work as intended.

Windows 10 KB4568831 is an optional patch and it won’t install automatically. If you don’t install the patch now, you’ll get Storage Space and other fixes in next Patch Tuesday update, which takes place on August 11.

Upgrade block notification

You may still see a compatibility hold on the Windows 10 version 2004 if Microsoft determines that your machine uses Storage Spaces or older drivers.

The current status of the upgrade block

In addition to Storage Spaces, Microsoft says the following issues have been resolved or mitigated in this optional update:

  • Issues with devices using older drivers of Nvidia GPU.
  • Problems when connecting to more than one Bluetooth device, such as a mouse, keyboard or headset.
  • Variable refresh rate may not work on devices with Intel iGPU.

While these issues have resolved or mitigated, Microsoft says compatibility hold for devices with above issues will be lifted in mid-August.

These fixes will allow Microsoft to finally expand the rollout of Windows 10 version 2004 and Windows Server version 2004.
