heavy-writes

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...

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...

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...

Microsoft and SSD vendors have opened an investigation after multiple independent testers and users reported that the August 12, 2025 Windows 11 cumulative update (KB5063878, OS Build 26100.4946) can cause some NVMe and SATA drives to stop responding, vanish from the operating system, and — in 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...

The Windows update ecosystem once again landed in the headlines this month after community researchers and multiple publications raised alarms about KB5063878 — the August 12, 2025 cumulative update for Windows 11 24H2 — and claims that a sustained-write workload can make some NVMe SSDs...

Microsoft’s August cumulative for Windows 11 (the KB5063878 rollup, OS Build 26100.4946) has been linked by independent testers and enthusiast outlets to a storage regression that can make some SSDs temporarily — and in a minority of cases permanently — disappear during sustained large writes...

Phison has publicly acknowledged that two recent Windows 11 security updates — KB5063878 and KB5062660 — are associated with a cluster of SSD failures that make drives vanish during large, sustained write operations, and the admission has sparked urgent questions about update testing, firmware...

Microsoft’s August cumulative for Windows 11 has left a trail of disrupted installs and disappearing NVMe drives, and Phison — maker of widely used SSD controllers including the PS5012‑E12 — has confirmed it is investigating reports that the updates KB5063878 and KB5062660 can trigger...

The August cumulative for Windows 11 — identified as KB5063878 (OS Build 26100.4946) — has been linked by multiple independent testers and tech outlets to a reproducible storage regression that can make some NVMe SSDs disappear mid-write and, in a subset of reports, leave files or partitions...

Microsoft’s August cumulative for Windows 11 24H2 (KB5063878) has been linked by independent testers and enthusiast communities to a reproducible storage regression in which certain NVMe SSDs can suddenly stop responding during sustained large writes, sometimes vanishing from Device Manager and...

Microsoft’s August cumulative for Windows 11 24H2 (KB5063878) has been tied to reports that, under specific heavy-write conditions, some NVMe SSDs — particularly Phison-controller models — and a small number of HDDs can become inaccessible and in some cases suffer file corruption, prompting...

Microsoft’s August cumulative for Windows 11 (KB5063878) shipped as a routine Secure Boot and quality update, but a scatter of user reports — concentrated in Japan and amplified across enthusiasts’ channels — now link the patch to serious SSD failures under heavy write workloads; the pattern...

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 August cumulative for Windows 11 (KB5063878) is at the center of a growing, technically consistent set of community reports: after installing the update, some users say NVMe SSDs can “vanish” during large, sustained file writes — sometimes leaving files corrupted, SMART/controller...

Microsoft’s latest cumulative for Windows 11 24H2 has been tied to a small but serious cluster of storage failures that can make NVMe SSDs disappear during heavy writes and, in a handful of cases, leave data unreadable — a scare that underscores why updating and backup discipline still matters...

Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been tied by multiple independent community tests and tech outlets to a serious storage regression: under sustained, large sequential writes some SSDs can stop responding, disappear from Windows, and — in a...
