Microsoft's recent security update KB5063878 for Windows 11 triggers solid-state drive failures during extensive data writing operations. X user @Necoru_cat identified this problem while updating Cyberpunk 2077 following the patch installation. The malfunction occurs when approximately 50 gigabytes of continuous data transfers to storage devices. Hard disk drives also experience similar problems beyond solid-state technology. Operating systems fail to detect affected drives after large file operations complete.
Multiple controller manufacturers face impact from this update across their storage products. SMI, Innogrit, Samsung, Phison, and Western Digital controllers exhibit these failures after extended write sessions. Drive partitions become inaccessible when users restart their computers following the malfunction. Eight specific storage models have received reports of this behavior from affected users. Storage driver regressions or kernel-level changes likely cause controllers to lock up during sequential write operations.
