Microsoft and Phison have now all but closed the book on the late‑August panic: after weeks of community reports, lab reproductions and headlines warning that Windows 11 24H2’s August cumulative (KB5063878) was “bricking” SSDs, thorough vendor and Microsoft testing found no reproducible link...

Phison has publicly acknowledged and replicated a key finding first raised by the PCDIY community: a wave of disappearing and allegedly “bricked” NVMe SSDs linked in timing to Windows 11’s August cumulative update (KB5063878) appears to have been driven, in at least some test cases, by...

Microsoft’s definitive update: after an internal review and partner testing, the company says the August 2025 Windows 11 security rollup did not directly corrupt or “brick” SSDs — but the incident has exposed a fragile interaction between OS updates, SSD controller firmware, and real-world...

Microsoft’s follow‑up investigation insists the August Windows 11 cumulative patch did not “brick” SSDs, but the story is far from a tidy conclusion: community test benches produced a repeatable failure fingerprint, controller vendor lab work failed to reproduce the fault, and Microsoft’s...

Phison’s terse lab summary — that it “was unable to reproduce” the reports that a mid‑August Windows 11 update could “brick” SSDs after more than 4,500 cumulative test hours — changed the tone of a fast‑moving controversy, but it did not close the book on a worrying, reproducible symptom set...

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...

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 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...

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 (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...

Microsoft’s August cumulative for Windows 11 — KB5063878 (OS Build 26100.4946) — has been linked by independent testers and enthusiast communities to a reproducible and severe storage fault: under sustained large sequential writes (reports center around the 50 GB range), certain NVMe SSDs—and a...
