storage regression

Microsoft’s August cumulative update for Windows 11 (KB5063878) has been linked by multiple independent testers and SSD vendors to a troubling storage regression: under sustained, large write workloads some SSDs temporarily vanish from the operating system — and in a subset of reports files...

Microsoft has opened an investigation after reports surfaced that the August 2025 Windows 11 cumulative/security update (commonly tracked as KB5063878, with related mentions of KB5062660) can cause some SSDs to stop responding or “vanish” from the operating system during sustained, heavy write...

Microsoft has acknowledged a new, practical regression introduced by the August cumulative update for Windows 11 (KB5063878) that can cause severe stuttering, dropped frames, and choppy audio/video in NDI‑based streaming flows — a problem that disproportionately affects multi‑PC capture 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...

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...

Phison has publicly disowned a circulated advisory that claimed Windows 11’s August cumulative update was uniquely “killing” Phison‑based SSDs, while the vendor — and several independent labs — simultaneously confirm an industry‑wide storage regression tied to the August 12, 2025 cumulative...

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...

Silicon Motion has told at least one forum poster that “none of our controllers are affected” by the Windows 11 storage regression that surfaced after Microsoft’s August 2025 cumulative update — but the larger picture remains unsettled and users should treat that single claim cautiously while...

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...

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...

Microsoft and SSD vendors are scrambling after multiple independent testers and users reported that a recent Windows 11 cumulative update can make NVMe SSDs vanish from the operating system during sustained large writes — a failure mode that in some cases has left files corrupted or drives...

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 the August 12, 2025 cumulative update for Windows 11 (KB5063878, OS Build 26100.4946) can trigger a storage regression that makes some SSDs disappear during sustained, large writes — a failure mode that, in a minority of reports...

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...

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 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...

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...

Microsoft’s August cumulative for Windows 11 — released as KB5063878 (OS Build 26100.4946) — is now at the center of a rapidly developing reliability story: independent testers and multiple tech outlets report that, under sustained large writes (commonly cited around 50 GB and above), some NVMe...

Microsoft’s latest Windows 11 cumulative update has been linked by multiple community tests and vendor advisories to a storage regression that, under specific conditions, can make some NVMe SSDs disappear during large sustained writes — risking data corruption or loss — and has reignited a...
