The August cumulative for Windows 11 24H2 (KB5063878) has been linked by multiple independent testers and specialist outlets to a reproducible storage regression that, under sustained large write workloads, can make some NVMe SSDs — and a small number of HDDs in isolated reports — disappear from...

Phison has warned customers that a circulated document purporting to come from the company — and claiming the recent Windows 11 security updates were uniquely breaking Phison-based SSDs — is a falsified communication, and the controller vendor says it is pursuing appropriate legal action while...
Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been linked by multiple community tests and specialist outlets to a narrow but severe storage regression in which some NVMe SSDs can suddenly become unresponsive or disappear during sustained, large writes — a...
