About this tag
The ssd-regression tag covers a specific storage bug introduced by the Windows 11 August 2025 cumulative update KB5063878 (OS Build 26100.4946). Multiple independent testers and tech outlets have confirmed that under sustained, large sequential writes, some NVMe SSDs can stop responding or disappear from Windows entirely. In a subset of cases, partitions become corrupted or data is left inaccessible. The issue primarily affects Windows 11 24H2 systems with certain controller families. Microsoft and SSD vendors have opened a coordinated investigation, and the regression has been linked to a broader pattern of storage woes in the 24H2 rollout, including earlier BSODs on Western Digital and SanDisk drives. Users with at-risk drives are advised to monitor vendor advisories and consider firmware updates.
