I'm up a gumtree without a paddle. I have been running around in circles for a week trying to get this solved.

Microsoft’s blunt conclusion — that the August Windows 11 cumulative update commonly tracked as KB5063878 is not the cause of reported SSD failures — closes one chapter in a fast-moving controversy but leaves crucial forensic questions unanswered for administrators and power users who handle...
Microsoft’s latest statement closes one chapter of an unsettling August patch cycle: after industry and community investigation, the company says the Windows 11 August 12, 2025 cumulative update commonly tracked as KB5063878 (OS Build 26100.4946) has not been shown to cause a platform‑wide...
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...

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...
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...
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’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...
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...
A mid‑August cumulative update for Windows 11 — KB5063878 (OS Build 26100.4946), released on August 12, 2025 — is being linked by multiple independent community tests and tech outlets to a storage regression that can render some SSDs inaccessible after sustained, large sequential writes, with...
