Windows 11’s 25H2 enablement package is currently triggering targeted upgrade blocks for systems using certain Western Digital and SanDisk NVMe SSDs — a conservative compatibility hold that echoes the same Host Memory Buffer (HMB) firmware problems first seen during the 24H2 rollout. Users who...

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...

Windows 11’s August cumulative update set off an alarm in enthusiast circles when a string of reproducible tests showed NVMe SSDs vanishing under sustained large writes — but the emerging, vendor‑validated explanation reframes the catastrophe as a narrower supply‑chain and firmware‑provenance...

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...

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...

Phison’s pre-release controller firmware has emerged as the most plausible explanation for the wave of NVMe SSD “vanishing” and bricking reports that followed Microsoft’s mid‑August Windows 11 cumulative updates — a finding that reframes the incident from a suspected OS regression into a...

Microsoft says its August Windows 11 security update (KB5063878) is not behind the recent wave of reports alleging SSDs and HDDs have been rendered inaccessible or corrupted, but the episode has exposed gaps in forensic clarity and left many users mistrustful of a conclusion drawn without a...

Microsoft and Phison have pushed back hard against a wave of social-media claims that the latest Windows 11 cumulative update is “bricking” NVMe SSDs — but the episode exposes a brittle edge case in modern storage stacks, a gap between telemetry and forensic proof, and practical steps every...

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’s audit of the August Windows 11 cumulative update has closed one chapter of an unusually noisy storage scare, but it has left behind a tangle of reproducible community tests, partial vendor confirmations, and unanswered forensic questions that IT teams and power users should still...

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 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 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 and a major controller vendor now say the August 2025 Windows 11 security update is not the smoking gun behind the bursts of SSD disappearances and alleged “bricking” reports that circulated through enthusiast forums — but the incident remains an important warning about fragile...

Microsoft’s latest position is unambiguous: after an internal review and partner-assisted testing, the company reports it “found no connection” between the August 2025 Windows 11 security update and the series of SSD disappearances and failures circulating on social media — but the empirical...

Less than two weeks after Microsoft pushed the August 12, 2025 cumulative update for Windows 11 (commonly tracked as KB5063878 for 24H2), a narrow but alarming failure profile began to circulate among hobbyist test benches and end users: during sustained large file transfers (commonly around 50...

Phison’s lab report and Microsoft’s telemetry have cooled the most sensational headlines about a mass “bricking” event, but the Windows 11 SSD failure story is far from closed: real, repeatable disappearance symptoms were documented by community testers and remain a live risk for certain NVMe...

Phison says its labs found no evidence that the Windows 11 24H2 cumulative update (KB5063878) or the related preview (KB5062660) will “brick” SSDs — a finding that calmed some headlines but left owners, data‑recovery specialists and IT managers with unresolved questions about a narrow...

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 potential storage disaster: users and hobbyist labs reported NVMe SSDs vanishing during large, sustained writes after installing the 24H2 cumulative update tracked as KB5063878 (and the related preview KB5062660), but Phison — the largest...
