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...

A wave of community test results and vendor confirmations this week has put the latest Windows 11 cumulative update under a harsh spotlight: several SSDs can disappear from Windows during sustained, large write operations after installing the August 12, 2025 update (KB5063878), with a...
Silicon Motion's early reassurance — that “so far, none of our controllers are affected” by the Windows 11 update that has been making some NVMe drives disappear under sustained writes — is an encouraging datapoint, but it is provisional and incomplete: the incident remains an active...
Windows 11’s August cumulative update (KB5063878) has been linked to a reproducible storage regression that can make certain SSDs and HDDs disappear under sustained large writes, and Silicon Motion — according to community‑sourced forum responses — reports none of its controllers have shown the...
Microsoft and several SSD vendors are investigating reports that the August 12, 2025 cumulative update for Windows 11 24H2 (KB5063878, OS Build 26100.4946) can trigger a reproducible storage regression where some SSDs vanish from the operating system during sustained, large sequential writes — a...
A wave of reproducible reports and a parallel burst of misinformation have combined to create one of the more consequential Patch Tuesday headaches in recent memory: Microsoft’s August 12, 2025 cumulative for Windows 11 (KB5063878) has been linked to SSDs disappearing under sustained, heavy...

Microsoft’s August Patch Tuesday delivered a surprise that quickly escalated from a support thread to a cross-industry incident: the Windows 11 cumulative update KB5063878 has been linked by multiple users to SSD and HDD failures, data corruption, and drives “vanishing” during heavy write...
Microsoft has acknowledged an active investigation after multiple community researchers, test benches and SSD vendors reported that the Windows 11 August cumulative (commonly tracked as KB5063878, OS Build 26100.4946) can cause certain SSDs to vanish from the operating system during sustained...
Phison has confirmed it is investigating a widespread storage regression tied to Windows 11’s August cumulative update (KB5063878) while simultaneously denouncing and legally challenging a circulated document that falsely claims to be an internal Phison report linking the problem exclusively to...

Microsoft and several SSD vendors are investigating reports that a recent Windows 11 cumulative update can cause some solid-state drives to stop responding or “vanish” from the operating system during sustained, large file writes — a failure mode that can leave files corrupted or, in a minority...
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...

Microsoft and SSD vendors have opened a coordinated investigation after multiple independent testers and users reported that the August Windows 11 cumulative update (KB5063878, OS Build 26100.4946) can, in rare but reproducible cases, cause some SSDs to stop responding or “vanish” during...
