Microsoft reportedly fixing SSD failures caused by Windows updates - Bleeping Computer

Microsoft has released a statement addressing reports that recent Windows 11 24H2 updates are causing serious storage drive issues across multiple SSD and HDD models.

The problem first surfaced when users noticed drives with Phison NAND controllers disappearing from their systems during heavy write operations after installing the KB5063878 security update and KB5062660 preview update. Testing reveals symptoms typically appear on SSDs with over 60% usage after approximately 50GB of continuous writing, with some drives becoming permanently inaccessible even after system restarts.

• Multiple drive brands affected including SanDisk Extreme Pro, Corsair Force MP600, and KIOXIA models with various controllers
• Microsoft and Phison are actively investigating the issue and working together on a solution
• Users should avoid large file transfers and extract compressed files in smaller batches as a temporary workaround
• The bug appears linked to a potential memory leak in the OS-buffered region affecting drive cache operations
