Microsoft has acknowledged a bug in its Storage Spaces feature that leads to file corruption, and is working on a resolution.

Storage Spaces is a features that uses regular hard drives to provide RAID-style storage redundancy. It’s also a useful way to create a pool of storage from a number of different drives.

Unfortunately for Microsoft, the latest Windows and Windows Server updates have a major bug impacting Storage Spaces.

“Devices using Parity 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,” reads the company’s support site. “When using some configurations, partitions for Parity Storage Spaces might show as RAW in Disk Manager.”

Unfortunately, “issues using or accessing their Storage Spaces” are just the beginning of the problem, as some users have also reported corrupted partitions and files.

At this time Microsoft does not have a permanent solution, only a workaround. This is just the latest in a string of issues Microsoft has had with data-eating bugs making their way into major OS releases. Here’s to hoping the company can get a handle on this one quickly.
