The newest Home windows 11 safety replace (KB5063878) has been linked to severe points affecting sure solid-state drives (SSDs). Experiences recommend that after putting in the replace, SSDs might turn into non-functional throughout massive sequential information writes, sometimes round 50GB or extra. Whereas the issue has not been formally confirmed by Microsoft or SSD producers, early accounts from customers and testers point out that the difficulty might trigger drives to vanish from the working system, rendering partitions inaccessible even after a system restart.

This malfunction might result in controller lock-ups, in the end inflicting the OS to cease recognizing the affected drives.
Given the potential dangers, customers with SSDs containing Phison controllers or the fashions listed above are suggested to keep away from extended sequential writing duties till extra info is offered.
