Phison says its lab work could not reproduce the Windows 11 SSD corruption reports that circulated after the August cumulative updates — but the episode exposes how fragile modern storage stacks can be when OS updates and controller firmware collide, and why backups, staged rollouts, and vendor...
Phison’s latest public stance changes the tone of what started as a panic: after industry-wide reports that a mid‑August Windows 11 cumulative update could cause NVMe SSDs to disappear during long writes, Phison says its internal testing — described as extensive — was unable to reproduce the...
Phison has confirmed it is investigating reports that a mid‑August Windows 11 cumulative update can trigger SSD instability — drives disappearing from Windows during sustained, heavy writes — and vendors, independent testers and Microsoft are coordinating forensic work while users are warned to...

Phison's latest public posture on the Windows 11 SSD scare shifts the narrative from an alleged vendor-level "bricking" spree to a coordinated investigation, but the episode leaves important questions about testing transparency, firmware distribution, and how quickly platform vendors communicate...
Phison’s latest public update frames the SSD problem that rocked Windows 11’s August rollout as an industry-wide, workload-dependent storage regression under investigation — not a single-vendor “bricking” event — but the episode exposes sharp risks in modern storage co‑engineering and offers...
Microsoft’s August cumulative packages for Windows 11 24H2 have been linked by independent testers, hardware vendors and multiple specialist outlets to a reproducible storage regression: certain SSDs (and a smaller set of HDDs) can stop responding or “vanish” from Windows during sustained, large...
