Microsoft says the recent reports that a Windows 11 cumulative update “bricked” consumer SSDs are not supported by its telemetry and lab findings, and vendor testing so far has failed to reproduce a fleet‑level failure tied to the August servicing wave tracked as KB5063878.
Background
The story...
BornCity’s latest dispatch raises a subtle but important question: did Microsoft quietly neutralize the wave of SSD failures reported from Japan after the August 2025 Windows 11 24H2 roll‑out, or did the alarm simply fade after vendors and Redmond concluded they could not reproduce a systemic...
Microsoft says its August Windows 11 security update KB5063878 is not to blame for a cluster of “vanishing” gaming SSD reports, but the episode has exposed a narrow, environment‑specific failure pattern that still leaves gamers and power users with real — and immediate — data‑safety decisions to...
Microsoft’s August Windows 11 cumulative update has ignited a fraught, still‑unresolved investigation after community testers and some independent labs reported that sustained heavy write operations could cause certain NVMe SSDs to disappear from Windows — and, in a minority of cases, become...
Windows 11’s August servicing wave briefly looked like a storage disaster: community testers reported NVMe drives disappearing mid-write after installing security updates KB5063878 and KB5062660, and many fingers pointed at SSDs using Phison controllers. After an industry investigation...
Phison’s latest test summary puts the disputed SSD failures tied to Windows 11 updates into a new, uneasy middle ground: vendors and Microsoft say they cannot reproduce a widespread “bricking” problem, while a small but alarming set of user reports continues to describe drives disappearing and...
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...
Within days of Microsoft’s August 2025 Patch Tuesday, a cluster of independent testers and community posts began documenting a worrying pattern: after installing the Windows 11 24H2 cumulative update (tracked as KB5063878, with a related preview package KB5062660), some NVMe SSDs momentarily or...
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...
Silicon Motion’s brief forum reply claiming that “none of our controllers are affected” landed as a hopeful note amid a widening industry investigation into Windows 11’s August 2025 cumulative update (KB5063878) — but the evidence available to date shows a complex, cross‑stack problem that...
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 cumulative (KB5063878) for Windows 11 24H2 has been linked by multiple independent testers and industry observers to a storage regression that can make some NVMe SSDs disappear during heavy writes — sometimes temporarily, sometimes with irrecoverable damage — and the safest...
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...
New Windows 11 24H2 cumulative updates released in August have been linked to a worrying, reproducible storage regression that can make some SSDs and a few HDDs vanish from the operating system during heavy, sustained writes — in a number of community tests the failure has led to corrupted or...

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...
Phison has publicly acknowledged the storage failures linked to Microsoft’s August 2025 Windows 11 cumulative updates (identified as KB5063878 and related KB5062660) and says it is investigating the reports with industry partners while controllers that “may have been affected” are under review...
